I have project built using laravel and a I have to build a function that counts all the complete quarters that are in the selected date range - the dates used are inserted via input.
Here are the quarters(i used numerical representations for the months)
01 - 03 first quarter
04 - 06 second quarter
07 - 09 third quarter
10 - 12 forth quarter
I would really appreciate your help,because I've been at it for an entire day now and basically have nothing to show for it,i thing I've been trying so hard i'm actually at the point where i'm so tired, i can t think straight.
I do have some code but it;s worthless, because it doesn't work, and any kind of idea or snippet of code is welcomed.
Thanks for your help in advance.
I managed to do this using multiple functions; basically, if this is needed for chart statistics, then a more specific approach might be the case.
I have done this in Laravel with timestamp dates as input (this code can be adapted for getting semesters also :) , it works and is already tested):
public static function getQuartersBetween($start_ts, $end_ts)
{
$quarters = [];
$months_per_year = [];
$years = self::getYearsBetween($start_ts, $end_ts);
$months = self::getMonthsBetween($start_ts, $end_ts);
foreach ($years as $year) {
foreach ($months as $month) {
if ($year->format('Y') == $month->format('Y')) {
$months_per_year[$year->format('Y')][] = $month;
}
}
}
foreach ($months_per_year as $year => $months) {
$january = new Date('01-01-' . $year);
$march = new Date('01-03-' . $year);
$april = new Date('01-04-' . $year);
$june = new Date('01-06-' . $year);
$july = new Date('01-07-' . $year);
$september = new Date('01-09-' . $year);
$october = new Date('01-10-' . $year);
$december = new Date('01-12-' . $year);
if (in_array($january, $months) && in_array($march, $months)) {
$quarter_per_year['label'] = 'T1 / ' . $year;
$quarter_per_year['start_day'] = $january->startOfMonth();
$quarter_per_year['end_day'] = $march->endOfMonth()->endOfDay();
array_push($quarters, $quarter_per_year);
}
if (in_array($april, $months) && in_array($june, $months)) {
$quarter_per_year['label'] = 'T2 / ' . $year;
$quarter_per_year['start_day'] = $april->startOfMonth();
$quarter_per_year['end_day'] = $june->endOfMonth()->endOfDay();
array_push($quarters, $quarter_per_year);
}
if (in_array($july, $months) && in_array($september, $months)) {
$quarter_per_year['label'] = 'T3 / ' . $year;
$quarter_per_year['start_day'] = $july->startOfMonth();
$quarter_per_year['end_day'] = $september->endOfMonth()->endOfDay();
array_push($quarters, $quarter_per_year);
}
if (in_array($october, $months) && in_array($december, $months)) {
$quarter_per_year['label'] = 'T4 / ' . $year;
$quarter_per_year['start_day'] = $october->startOfMonth();
$quarter_per_year['end_day'] = $december->endOfMonth()->endOfDay();
array_push($quarters, $quarter_per_year);
}
}
return $quarters;
}
and getting the years between:
public static function getYearsBetween($start_ts, $end_ts, $full_period = false)
{
$return_data = [];
$current = mktime(0, 0, 0, date('m', $start_ts), date('d', $start_ts), date('Y', $start_ts));
while ($current < $end_ts) {
$temp_date = $current;
$year = new Date($temp_date);
$return_data[] = $year;
$current = strtotime("+1 year", $current); // add a year
}
if ($full_period) {
$return_data[] = $end_ts;
}
return $return_data;
}
, also getting the months needed
public static function getMonthsBetween($start_ts, $end_ts, $full_period = false)
{
$return_data = $month_list = [];
$current = mktime(0, 0, 0, date('m', $start_ts), date('d', $start_ts), date('Y', $start_ts));
while ($current <= $end_ts) {
$temp_date = $current;
$date = new Date($temp_date);
$month_list[] = $date;
$current = strtotime("+1 month", $current); // add a month
}
$start_date_last_month = new Date(array_first($month_list));
$start_date_last_month = $start_date_last_month->startOfMonth()->format('m-d');
$temp_end_date = new Date($start_ts);
$temp_end_date = $temp_end_date->format('m-d');
if ($start_date_last_month < $temp_end_date) {
array_shift($month_list);
}
$end_date_last_month = new Date(end($month_list));
$current_day_month = $end_date_last_month->endOfMonth()->format('m-d');
$temp_end_date = new Date($end_ts);
$end_day_of_month = $temp_end_date->format('m-d');
if ($end_day_of_month < $current_day_month) {
array_pop($month_list);
}
if (count($month_list) == 0) {
$month_list[] = $end_date_last_month->subMonth();
}
$return_data = $month_list;
if ($full_period) {
$return_data[] = $end_ts;
}
return $return_data;
}
You can do something like in this example:
$February = 2;
$October = 10;
$completedQuarters = ceil($October/3) - ceil($February/3); // = 3
What about the quarter in which the date range starts, should it also count? If it should only count if it begins in the first month of a quarter you can check for it like this:
$completedQuarters = ceil($October/3) - ceil($February/3) -1; // = 2
if($February-1%3 == 0) $completedQuarters += 1;
You´re description is not very clear, let me know if that´s what you had in mind.
Not sure if the following is what you are meaning but might be useful
$date_start='2015/03/12';
$date_end='2017/11/14';
$timezone=new DateTimeZone('Europe/London');
$start=new DateTime( $date_start, $timezone );
$end=new DateTime( $date_end, $timezone );
$difference = $end->diff( $start );
$months = ( ( $difference->format('%y') * 12 ) + $difference->format('%m') );
$quarters = intval( $months / 3 );
printf( 'Quarters between %s and %s is %d covering %d months', $start->format('l, jS F Y'), $end->format('l, jS F Y'), $quarters, $months );
/*
This will output
----------------
Quarters between Thursday, 12th March 2015 and Tuesday, 14th November 2017 is 10 covering 32 months
*/
Something like this in the function and you should be set.
use Carbon\Carbon;
$first = Carbon::parse('2012-1-1'); //first param
$second = Carbon::parse('2014-9-15'); //second param
$fY = $first->year; //2012
$fQ = $first->quarter; //1
$sY = $second->year; //2014
$sQ = $second->quarter; //3
$n = 0; //the number of quarters we have counted
$i = 0; //an iterator we will use to determine if we are in the first year
for ($y=$fY; $y < $sY; $y++, $i++) { //for each year less than the second year (if any)
$s = ($i > 0) ? 1 : $fQ; //determine the starting quarter
for ($q=$s; $q <= 4; $q++) { //for each quarter
$n++; //count it
}
}
if ($sY > $fY) { //if both dates are not in the same year
$n = $n + $sQ; //total is the number of quarters we've counted plus the second quarter value
} else {
for ($q=$fQ; $q <= $sQ; $q++) { //for each quarter between the first quarter and second
$n++; //count it
}
}
print $n; //the value to return (11)
I have an array of random dates (not coming from MySQL). I need to group them by the week as Week1, Week2, and so on upto Week5.
What I have is this:
$dates = array('2015-09-01','2015-09-05','2015-09-06','2015-09-15','2015-09-17');
What I need is a function to get the week number of the month by providing the date.
I know that I can get the weeknumber by doing
date('W',strtotime('2015-09-01'));
but this week number is the number between year (1-52) but I need the week number of the month only, e.g. in Sep 2015 there are 5 weeks:
Week1 = 1st to 5th
Week2 = 6th to 12th
Week3 = 13th to 19th
Week4 = 20th to 26th
Week5 = 27th to 30th
I should be able to get the week Week1 by just providing the date
e.g.
$weekNumber = getWeekNumber('2015-09-01') //output 1;
$weekNumber = getWeekNumber('2015-09-17') //output 3;
I think this relationship should be true and come in handy:
Week of the month = Week of the year - Week of the year of first day of month + 1
We also need to make sure that "overlapping" weeks from the previous year are handeled correctly - if January 1st is in week 52 or 53, it should be counted as week 0. In a similar fashion, if a day in December is in the first week of the next year, it should be counted as 53. (Previous versions of this answer failed to do this properly.)
<?php
function weekOfMonth($date) {
//Get the first day of the month.
$firstOfMonth = strtotime(date("Y-m-01", $date));
//Apply above formula.
return weekOfYear($date) - weekOfYear($firstOfMonth) + 1;
}
function weekOfYear($date) {
$weekOfYear = intval(date("W", $date));
if (date('n', $date) == "1" && $weekOfYear > 51) {
// It's the last week of the previos year.
return 0;
}
else if (date('n', $date) == "12" && $weekOfYear == 1) {
// It's the first week of the next year.
return 53;
}
else {
// It's a "normal" week.
return $weekOfYear;
}
}
// A few test cases.
echo weekOfMonth(strtotime("2020-04-12")) . " "; // 2
echo weekOfMonth(strtotime("2020-12-31")) . " "; // 5
echo weekOfMonth(strtotime("2020-01-02")) . " "; // 1
echo weekOfMonth(strtotime("2021-01-28")) . " "; // 5
echo weekOfMonth(strtotime("2018-12-31")) . " "; // 6
To get weeks that starts with sunday, simply replace date("W", ...) with strftime("%U", ...).
You can use the function below, fully commented:
/**
* Returns the number of week in a month for the specified date.
*
* #param string $date
* #return int
*/
function weekOfMonth($date) {
// estract date parts
list($y, $m, $d) = explode('-', date('Y-m-d', strtotime($date)));
// current week, min 1
$w = 1;
// for each day since the start of the month
for ($i = 1; $i < $d; ++$i) {
// if that day was a sunday and is not the first day of month
if ($i > 1 && date('w', strtotime("$y-$m-$i")) == 0) {
// increment current week
++$w;
}
}
// now return
return $w;
}
The corect way is
function weekOfMonth($date) {
$firstOfMonth = date("Y-m-01", strtotime($date));
return intval(date("W", strtotime($date))) - intval(date("W", strtotime($firstOfMonth)));
}
I have created this function on my own, which seems to work correctly. In case somebody else have a better way of doing this, please share.. Here is what I have done.
function weekOfMonth($qDate) {
$dt = strtotime($qDate);
$day = date('j',$dt);
$month = date('m',$dt);
$year = date('Y',$dt);
$totalDays = date('t',$dt);
$weekCnt = 1;
$retWeek = 0;
for($i=1;$i<=$totalDays;$i++) {
$curDay = date("N", mktime(0,0,0,$month,$i,$year));
if($curDay==7) {
if($i==$day) {
$retWeek = $weekCnt+1;
}
$weekCnt++;
} else {
if($i==$day) {
$retWeek = $weekCnt;
}
}
}
return $retWeek;
}
echo weekOfMonth('2015-09-08') // gives me 2;
function getWeekOfMonth(DateTime $date) {
$firstDayOfMonth = new DateTime($date->format('Y-m-1'));
return ceil(($firstDayOfMonth->format('N') + $date->format('j') - 1) / 7);
}
Goendg solution does not work for 2016-10-31.
function weekOfMonth($strDate) {
$dateArray = explode("-", $strDate);
$date = new DateTime();
$date->setDate($dateArray[0], $dateArray[1], $dateArray[2]);
return floor((date_format($date, 'j') - 1) / 7) + 1;
}
weekOfMonth ('2015-09-17') // returns 3
Given the time_t wday (0=Sunday through 6=Saturday) of the first of the month in firstWday, this returns the (Sunday-based) week number within the month:
weekOfMonth = floor((dayOfMonth + firstWday - 1)/7) + 1
Translated into PHP:
function weekOfMonth($dateString) {
list($year, $month, $mday) = explode("-", $dateString);
$firstWday = date("w",strtotime("$year-$month-1"));
return floor(($mday + $firstWday - 1)/7) + 1;
}
You can also use this simple formula for finding week of the month
$currentWeek = ceil((date("d",strtotime($today_date)) - date("w",strtotime($today_date)) - 1) / 7) + 1;
ALGORITHM :
Date = '2018-08-08' => Y-m-d
Find out day of the month eg. 08
Find out Numeric representation of the day of the week minus 1 (number of days in week) eg. (3-1)
Take difference and store in result
Subtract 1 from result
Divide it by 7 to result and ceil the value of result
Add 1 to result eg. ceil(( 08 - 3 ) - 1 ) / 7) + 1 = 2
My function. The main idea: we would count amount of weeks passed from the month's first date to current. And the current week number would be the next one. Works on rule: "Week starts from monday" (for sunday-based type we need to transform the increasing algorithm)
function GetWeekNumberOfMonth ($date){
echo $date -> format('d.m.Y');
//define current year, month and day in numeric
$_year = $date -> format('Y');
$_month = $date -> format('n');
$_day = $date -> format('j');
$_week = 0; //count of weeks passed
for ($i = 1; $i < $_day; $i++){
echo "\n\n-->";
$_newDate = mktime(0,0,1, $_month, $i, $_year);
echo "\n";
echo date("d.m.Y", $_newDate);
echo "-->";
echo date("N", $_newDate);
//on sunday increasing weeks passed count
if (date("N", $_newDate) == 7){
echo "New week";
$_week += 1;
}
}
return $_week + 1; // as we are counting only passed weeks the current one would be on one higher
}
$date = new DateTime("2019-04-08");
echo "\n\nResult: ". GetWeekNumberOfMonth($date);
$month = 6;
$year = 2021;
$week = date("W", strtotime($year . "-" . $month ."-01"));
$str='';
$str .= date("d-m-Y", strtotime($year . "-" . $month ."-01")) ."to";
$unix = strtotime($year."W".$week ."+1 week");
while(date("m", $unix) == $month){
$str .= date("d-m-Y", $unix-86400) . "|";
$str .= date("d-m-Y", $unix) ."to";
$unix = $unix + (86400*7);
}
$str .= date("d-m-Y", strtotime("last day of ".$year . "-" . $month));
$weeks_ar = explode('|',$str);
echo '<pre>'; print_r($weeks_ar);
working fine.
// Current week of the month starts with Sunday
$first_day_of_the_week = 'Sunday';
$start_of_the_week1 = strtotime("Last $first_day_of_the_week");
if (strtolower(date('l')) === strtolower($first_day_of_the_week)) {
$start_of_the_week1 = strtotime('today');
}
$end_of_the_week1 = $start_of_the_week1 + (60 * 60 * 24 * 7) - 1;
// Get the date format
print date('Y-m-d', $start_of_the_week1) . ' 00:00:00';
print date('Y-m-d', $end_of_the_week1) . ' 23:59:59';
// self::DAYS_IN_WEEK = 7;
function getWeeksNumberOfMonth(): int
{
$currentDate = new \DateTime();
$dayNumberInMonth = (int) $currentDate->format('j');
$dayNumberInWeek = (int) $currentDate->format('N');
$dayNumberToLastSunday = $dayNumberInMonth - $dayNumberInWeek;
$daysCountInFirstWeek = $dayNumberToLastSunday % self::DAYS_IN_WEEK;
$weeksCountToLastSunday = ($dayNumberToLastSunday - $daysCountInFirstWeek) / self::DAYS_IN_WEEK;
$weeks = [];
array_push($weeks, $daysCountInFirstWeek);
for ($i = 0; $i < $weeksCountToLastSunday; $i++) {
array_push($weeks, self::DAYS_IN_WEEK);
}
array_push($weeks, $dayNumberInWeek);
if (array_sum($weeks) !== $dayNumberInMonth) {
throw new Exception('Logic is not valid');
}
return count($weeks);
}
Short variant:
(int) (new \DateTime())->format('W') - (int) (new \DateTime('first day of this month'))->format('W') + 1;
There is a many solutions but here is one my solution that working well in the most cases.
function current_week ($date = NULL) {
if($date) {
if(is_numeric($date) && ctype_digit($date) && strtotime(date('Y-m-d H:i:s',$date)) === (int)$date)
$unix_timestamp = $date;
else
$unix_timestamp = strtotime($date);
} else $unix_timestamp = time();
return (ceil((date('d', $unix_timestamp) - date('w', $unix_timestamp) - 1) / 7) + 1);
}
It accept unix timestamp, normal date or return current week from the time() if you not pass any value.
Enjoy!
I know this an old post but i have an idea!
$datetime0 = date_create("1970-01-01");
$datetime1 = date_create(date("Y-m-d",mktime(0,0,0,$m,"01",$Y)));
$datetime2 = date_create(date("Y-m-d",mktime(0,0,0,$m,$d,$Y)));
$interval1 = date_diff($datetime0, $datetime1);
$daysdiff1= $interval1->format('%a');
$interval2 = date_diff($datetime0, $datetime2);
$daysdiff2= $interval2->format('%a');
$week1=round($daysdiff1/7);
$week2=round($daysdiff2/7);
$WeekOfMonth=$week2-$week1+1;
$date = new DateTime('first Monday of this month');
$thisMonth = $date->format('m');
$mondays_arr = [];
// Get all the Mondays in the current month and store in array
while ($date->format('m') === $thisMonth) {
//echo $date->format('Y-m-d'), "\n";
$mondays_arr[] = $date->format('d');
$date->modify('next Monday');
}
// Get the day of the week (1-7 from monday to sunday)
$day_of_week = date('N') - 1;
// Get the day of month (1 to 31)
$current_week_monday_date = date('j') - $day_of_week;
/*$day_of_week = date('N',mktime(0, 0, 0, 2, 11, 2020)) - 1;
$current_week_monday_date = date('j',mktime(0, 0, 0, 2, 11, 2020)) - $day_of_week;*/
$week_no = array_search($current_week_monday_date,$mondays_arr) + 1;
echo "Week No: ". $week_no;
How about this function making use of PHP's relative dates?
This function assumes the week ends on Saturday. But this can be changed easily.
function get_weekNumMonth($date) {
$CI = &get_instance();
$strtotimedate = strtotime($date);
$firstweekEnd = date('j', strtotime("FIRST SATURDAY OF " . date("F", $strtotimedate) . " " . date("Y", $strtotimedate)));
$cutoff = date('j', strtotime($date));
$weekcount = 1;
while ($cutoff > $firstweekEnd) {
$weekcount++;
$firstweekEnd += 7; // move to next week
}
return $weekcount;
}
This function returns the integer week number of the current month. Weeks always start on Monday and counting always starts with 1.
function weekOfmonth(DateTime $date)
{
$dayFirstMonday = date_create('first monday of '.$date->format('F Y'))->format('j');
return (int)(($date->format('j') - $dayFirstMonday +7)/7) + ($dayFirstMonday == 1 ? 0 : 1);
}
Example of use
echo weekOfmonth(new DateTime("2020-04-12")); //2

{
$dayFirstMonday = date_create('first monday of '.$date->format('F Y'))->format('j');
return (int)(($date->format('j') - $dayFirstMonday +7)/7) + ($dayFirstMonday == 1 ? 0 : 1);
}
$dt = date_create('1900-01-01');
$end = date_create('2038-01-02');
$countOk = 0;
$countError = 0;
for(;$dt < $end; $dt->modify('+1 Day')){
$ts = $dt->getTimestamp();
if(weekOfmonth($dt) === weekOfMonthAnders($ts)){
++$countOk;
}
else {
++$countError;
}
}
echo $countOk.' compare ok, '.$countError.' errors';
Result: 50405 compare ok, 0 errors
I took the visual approach (like how we do it in the real world). Instead of using formulas or what not, I solved it (or at least I think I did) by visualizing a literal calendar and then putting the dates in a multidimensional array. The first dimension corresponds to the week.
I hope someone can check if it stands your tests. Or help someone out with a different approach.

I am working on a "cut-off" date and I need to set it on every month. Say, I set the cut-off date to August 25 for this year, then it should be September 25, October 25 and so on till the year ends.
Here's the code I have:
$now = "2015-08-25";
$nextDate = getCutoffDate($now);
echo $nextDate;
function getCutoffDate($start_date)
{
$date_array = explode("-",$start_date); // split the array
// var_dump($date_array);
$year = $date_array[0];
$month = $date_array[1];
$day = $date_array[2];
/*if (date('n', $now)==12)
{
return date("Y-m-d",strtotime(date("Y-m-d", $start_date) . "+1 month"));
}*/
if (date("d") <= $day) {
$billMonth = date_format(date_create(), 'm');
}
else{
$billMonth = date_format(date_modify(date_create(), 'first day of next month'), 'm');
}
// echo date("d").' '. $billMonth.'<br>';
$billMonthDays = cal_days_in_month(CAL_GREGORIAN, ($billMonth), date("Y"));
// echo $billMonthDays.'<br>';
if ($billMonthDays > $day) {
$billDay = $day;
} else {
$billDay = $billMonthDays;
}
}
I got this from here: http://www.midwesternmac.com/blogs/jeff-geerling/php-calculating-monthly
It returns the same date for the next month only, but how do I get the specific date of EACH month of the current year? Kindly leave your thoughts. Still a newbie here, sorry.
In that case, this should be enough:
<?php
for($i=8; $i<=12; $i++) {
echo sprintf('25-%02d-2015', $i) . '<br>';
}
but if you need more flexible way:
<?php
$date = new DateTime('25-08-2015');
function getCutoffDate($date) {
$days = cal_days_in_month(CAL_GREGORIAN, $date->format('n'), $date->format('Y'));
$date->add(new DateInterval('P' . $days .'D'));
return $date;
}
for($i = 0; $i < 5; $i++) {
$date = getCutoffDate($date);
echo $date->format('d-m-Y') . '<br>';
}
This should print:
25-09-2015
25-10-2015
25-11-2015
25-12-2015
25-01-2016
I need to Write a function named countDays which takes a single parameter named dateinstring which is string in the form ”MM.DD.YYY” represent a real date value. The function should print to the console the number of days from the beginning of the year specified in dateInString until the date represented in dateInString. If the value of dateInString is invalid, the function should print ”Bad format” to the console.
I have written the code as below :
function countDays($dateInString){
date_default_timezone_set('America/Los_Angeles');
$date = explode('.', $dateInString);
if(count($date) == 3 && checkdate($date[0], $date[1], $date[2])){
$formatted_date = $date[2].'-'.$date[0].'-'.$date[1].'00:00:00';
$diff = strtotime($formatted_date).'-'.strtotime($date[2].'-01-01 00:00:00');
echo round($diff/86400)+1;
}
else {
echo 'Bad format';
}
};
countDays('1.15.2014');
But the above code seems that not giving the correct output. It is about 33% correct. But where is the problem with this code ? Please help me!!!
$diff = strtotime($formatted_date).'-'.strtotime($date[2].'-01-01 00:00:00');
Change to
$diff = strtotime($formatted_date) - strtotime($date[2].'-01-01 00:00:00');
You made the minus symbol a string instead of an operator.
You could try it this way
function countDays($dateInString) {
date_default_timezone_set('America/Los_Angeles');
$date = explode('.', $dateInString);
if (checkdate($date[0], $date[1], $date[2])) {
$year_start = mktime(0, 0, 0, 1, 1, $date[2]);
$your_date = mktime(0,0,0,$date[0], $date[1], $date[2]);
$diff = $your_date - $year_start;
echo floor($diff /(60*60*24));
} else {
echo "Bad date supplied";
}
}
A better approach would be to use the DateTime class. I haven't included the validation in this, but i suggest you use regex for that.
function countDays($dateInString){
$parts = explode('.', $dateInString);
$date = new DateTime($parts[2] . '-' . $parts[0] . '-' . $parts[1]);
$compare = new DateTime( $date->format('Y') . '-01-01' );
$interval = $date->diff($compare);
return $interval->format('%a');
}
echo countDays('09.15.2014');
Check this out.
function countDays($dateInString){
date_default_timezone_set('America/Los_Angeles');
$date = explode('.', $dateInString);
if(count($date) == 3 && checkdate($date[0], $date[1], $date[2])){
$formatted_date = strtotime($date[2].'/'.$date[0].'/'.$date[1]);
$endTimeStamp = strtotime("2014/01/01");
$timeDiff = abs($endTimeStamp - $formatted_date);
echo round(intval($timeDiff/86400));
}
else {
echo 'Bad format';
}
};
countDays('01.01.2014');
Is there any php function where i can get exact date, by providing week number of the month and day as,
function required_date($week_num, $day) {
// should return 20th of September, if i pass (3, 'Friday')
}
I am getting week number of the month as
ceil(substr(date('Y-m-d'), -2) / 7);
and day as,
date('l');
Any help, please!
function required_date($week_num, $day) {
$week_of_year = sprintf('%02d', date('W', strtotime(date('Y-m-01'))) + $week_num);
$day_of_week = date('N', strtotime($day));
$timestamp = strtotime(date('Y') . '-W' . $week_of_year . '-' . $day_of_week);
return $timestamp;
}
$timestamp = required_date(3, 'friday');
echo date('Y-m-d', $timestamp);
try this:
date('Y-m-d', strtotime('W' . $week_num . ' ' . $day));
How about
function required_date($week_num, $day)
{
return date('Y-m-') . substr('0' . (($week_num - 1) * 7 + date('N', strtotime($day))) + 1, -2);
}
var_dump(required_date(3, 'Friday'));
var_dump(required_date(4, 'Friday'));
