I want to add 12 months to my date. My start date is 02/29/2020 and I want to add 12 months to this.
Code:
$startdate = '02/29/2020';
date('m/d/Y', strtotime('+12 months', strtotime($startdate)));
Output:
03/01/2021
I used this code to add 12 months but the output is 03/01/2021, when the real output should be 02/28/2020.
Have a look!
function add_months($months, DateTime $dateObject)
{
$next = new DateTime($dateObject->format('Y-m-d'));
$next->modify('last day of +'.$months.' month');
if($dateObject->format('d') > $next->format('d')) {
return $dateObject->diff($next);
} else {
return new DateInterval('P'.$months.'M');
}
}
function getCalculatedDate($d1, $months)
{
$date = new DateTime($d1);
// call second function to add the months
$newDate = $date->add(add_months($months, $date));
//formats final date to m/d/Y form
$dateReturned = $newDate->format('m/d/Y');
return $dateReturned;
}
An example would be:-
$startDate = '02/29/2020';
$nMonths = 12; // choose how many months you want to add
$finalDate = getCalculatedDate($startDate, $nMonths); // output: 02/28/2021
This way you will get the output of 02/28/2021
$startdate = '02/29/2020';
$date = date('m/d/Y', strtotime($startdate . '+365 days'));
using DateTime and DateInterval objects leads to 03/01/2021
$date = new \DateTime('02/29/2020');
$date->add(new \DateInterval('P12M'));
echo $date->format('m/d/Y');
for me 03/01/2021 is not always a bad answer
Can anyone help create this logic? Kind of difficult to explain...
Looking to take a date, add 3 days then select the next date based on a database value.
Say we start with:
$end_date = "2017-08-23 23:59:59"
$payday = 5; //1=monday, 2=tuesday, 3=wednesday, 4=thursday, 5=friday
//And we want to calculate $paydate:
$temp_date = $end_date + 3 days;
$pay_date = the first $payday(day of week) after $temp_date
Any ideas how to write this in php? This one is stumping me. Thanks!
To add three days you can do this:
$date = new DateTime('2017-08-23 23:59:59');
$date->add(new DateInterval('P3D'));
$date->modify("next friday");
echo $date->format('Y-m-d') . "\n";
You could also use a lookup table, or array, that matches number to named days of the week and use something like $date->modify("next $days[$payday]");
where
$days = [ [1] => "monday",
.... etc
How about this? It will get a date, add 3 days, and then loop through the next days until it finds a day in the $days array (which you can get from a database):
<?php
$date = new DateTime('2017-08-23 23:59:59');
function nextPayday($date) {
$date->add(new DateInterval('P3D'));
echo "Date + 3 days: ".$date->format('D Y-m-d') . "<br>";
$payDate = $date->add(new DateInterval('P1D'));
$days = ["1", "2", "3", "4", "5"];
while (!in_array($payDate->format("N"), $days)) {
$payDate->add(new DateInterval('P1D'));
}
return $payDate->format("D Y-m-d");
}
echo "Date + 3 days: ".$date->format('D Y-m-d') . "<br>";
echo "Next payday: ".nextPayday($date);
Demo
Or, if you need to find a next specific day, use this function instead:
function nextPayday($date) {
$date->add(new DateInterval('P3D'));
echo "Date + 3 days: ".$date->format('D Y-m-d') . "<br>";
$payDate = $date->add(new DateInterval('P1D'));
$day = "5";
while ($payDate->format("N") !== $day) {
$payDate->add(new DateInterval('P1D'));
}
return $payDate->format("D Y-m-d");
}
Jeff, take a look at Carbon which extends PHP's DateTime object.
It allows you to deal with dates in a very clean and intuitive way. Based on your example:
$date = Carbon::parse('next monday')->toDateString();
Adjust that to your exact case.
Another version to achieve the objective:
function nextPayday($dateString, $paydayNum) {
$paydays = [
1=>'monday',
2=>'tuesday',
3=>'wednesday',
4=>'thursday',
5=>'friday'
];
$temp_date_stamp = date('d-m-Y H:i:s', strtotime($dateString.' +3 days'));
$pay_date_stamp = strtotime('first '.$paydays[$paydayNum].' '.$temp_date_stamp);
return date('d-m-Y H:i:s', $pay_date_stamp);
}
$end_date = "2017-08-23 23:59:59";
$payday = 5;
echo nextPayday($end_date, $payday);
result:
01-09-2017 23:59:59
I am trying to calculate a person's age from their date of birth on an ExpressionEngine site.
The following code works on my local test site but the server is using an older version of PHP (5.2.17) so I amgetting errors.
Could someone suggest what code I would need to use instead?
{exp:channel:entries channel='zoo_visitor'}
<?php
$dob = new DateTime('{member_birthday format='%Y-%m-%d'}');
$now = new DateTime('now');
// This returns a DateInterval object.
$age = $now->diff($dob);
// You can output the date difference however you choose.
echo 'This person is ' .$age->format('%y') .' years old.';
?>
{/exp:channel:entries}
Your current code won't work because DateTime::diff was introduced in PHP 5.3.0.
Normally date arithmetic is quite tricky because you have to take into account timezones, DST and leap years, but for a task as simple as calculating a "whole year" difference you can do it quite easily.
The idea is that the result is equal to the end date's year minus the start date's year, and if the start date's month/day is earlier inside the year than the end date's you should subtract 1 from that. The code:
$dob = new DateTime('24 June 1940');
$now = new DateTime('now');
echo year_diff($now, $dob);
function year_diff($date1, $date2) {
list($year1, $dayOfYear1) = explode(' ', $date1->format('Y z'));
list($year2, $dayOfYear2) = explode(' ', $date2->format('Y z'));
return $year1 - $year2 - ($dayOfYear1 < $dayOfYear2);
}
See it in action. Note how the result increases by 1 on the exact same day as specified for the birthday.
$dob = strtotime('{member_birthday format='%Y-%m-%d'}');
$now = time();
echo 'This person is ' . (1970 - date('Y', ($now - $dob))) .' years old.';
You can use the diff only above PHP 5.3
You can try with modify, it works on 5.2
$age = $now->modify('-' . $dob->format('Y') . 'year');
After much search I have found the answer:
<?php
//date in mm/dd/yyyy format
$birthDate = "{member_birthday format='%m/%d/%Y'}";
//explode the date to get month, day and year
$birthDate = explode("/", $birthDate);
//get age from date or birthdate
$age = (date("md",
date("U",
mktime(0,
0,
0,
$birthDate[0],
$birthDate[1],
$birthDate[2])
)
)
> date("md")
? ((date("Y") - $birthDate[2]) - 1)
: (date("Y") - $birthDate[2]));
echo $age;
?>
The calculations which only use day of year are off by one in some corner cases: They show 1 year for 2012-02-29 and 2011-03-01, while this should be 0 years (and 11 months and 28 days). A possible solution which takes into account leap years is:
<?php
function calculateAge(DateTime $birthDate, DateTime $now = null) {
if ($now == null) {
$now = new DateTime;
}
$age = $now->format('Y') - $birthDate->format('Y');
$dm = $now->format('m') - $birthDate->format('m');
$dd = $now->format('d') - $birthDate->format('d');
if ($dm < 0 || ($dm == 0 && $dd < 0)) {
$age--;
}
return $age;
}
echo calculateAge(new DateTime('2011-04-01'), new DateTime('2012-03-29'));
user579984's solution works, too, though.
$birthday = '1983-03-25';
$cm = date('Y', strtotime($birthday));
$cd = date('Y', strtotime('now'));
$res = $cd - $cm;
if (date('m', strtotime($birthday)) > date('m', strtotime('now')))
$res--;
else if ((date('m', strtotime($birthday)) == date('m', strtotime('now'))) &&
(date('d', strtotime($birthday)) > date('d', strtotime('now'))))
$res--;
echo $res;
I've been using this and it's never let me down. YYYYMMDD being the person's birthday.
$age = floor((date('Ymd') - 'YYYYMMDD') / 10000);
If you want to be more strict you could convert the dates to integers using the intval function or preceding the dates with (int).
I want to take a date and work out its week number.
So far, I have the following. It is returning 24 when it should be 42.
<?php
$ddate = "2012-10-18";
$duedt = explode("-",$ddate);
$date = mktime(0, 0, 0, $duedt[2], $duedt[1],$duedt[0]);
$week = (int)date('W', $date);
echo "Weeknummer: ".$week;
?>
Is it wrong and a coincidence that the digits are reversed? Or am I nearly there?
Today, using PHP's DateTime objects is better:
<?php
$ddate = "2012-10-18";
$date = new DateTime($ddate);
$week = $date->format("W");
echo "Weeknummer: $week";
It's because in mktime(), it goes like this:
mktime(hour, minute, second, month, day, year);
Hence, your order is wrong.
<?php
$ddate = "2012-10-18";
$duedt = explode("-", $ddate);
$date = mktime(0, 0, 0, $duedt[1], $duedt[2], $duedt[0]);
$week = (int)date('W', $date);
echo "Weeknummer: " . $week;
?>
$date_string = "2012-10-18";
echo "Weeknummer: " . date("W", strtotime($date_string));
Use PHP's date function
http://php.net/manual/en/function.date.php
date("W", $yourdate)
This get today date then tell the week number for the week
<?php
$date=date("W");
echo $date." Week Number";
?>
Just as a suggestion:
<?php echo date("W", strtotime("2012-10-18")); ?>
Might be a little simpler than all that lot.
Other things you could do:
<?php echo date("Weeknumber: W", strtotime("2012-10-18 01:00:00")); ?>
<?php echo date("Weeknumber: W", strtotime($MY_DATE)); ?>
Becomes more difficult when you need year and week.
Try to find out which week is 01.01.2017.
(It is the 52nd week of 2016, which is from Mon 26.12.2016 - Sun 01.01.2017).
After a longer search I found
strftime('%G-%V',strtotime("2017-01-01"))
Result: 2016-52
https://www.php.net/manual/de/function.strftime.php
ISO-8601:1988 week number of the given year, starting with the first week of the year with at least 4 weekdays, with Monday being the start of the week. (01 through 53)
The equivalent in mysql is DATE_FORMAT(date, '%x-%v')
https://www.w3schools.com/sql/func_mysql_date_format.asp
Week where Monday is the first day of the week (01 to 53).
Could not find a corresponding solution with DateTime.
At least not without solutions like "+1day, last monday".
Edit: since strftime is now deprecated, maybe you can also use date.
Didn't verify it though.
date('o-W',strtotime("2017-01-01"));
I have tried to solve this question for years now, I thought I found a shorter solution but had to come back again to the long story. This function gives back the right ISO week notation:
/**

function calcweek($date) {
// 1. Convert input to $year, $month, $day

$year = date("Y", $dateset);
$month = date("m", $dateset);
$day = date("d", $dateset);
$referenceday = getdate(mktime(0,0,0, $month, $day, $year));
$jan1day = getdate(mktime(0,0,0,1,1,$referenceday[year]));
// 2. check if $year is a leapyear

// 10. output iso week number (YYWW)
return ($yearnumber-2000)*100+$weeknumber;
}
I found out that my short solution missed the 2018-12-31 as it gave back 1801 instead of 1901. So I had to put in this long version which is correct.
How about using the IntlGregorianCalendar class?
Requirements: Before you start to use IntlGregorianCalendar make sure that libicu or pecl/intl is installed on the Server.
So run on the CLI:
php -m
If you see intl in the [PHP Modules] list, then you can use IntlGregorianCalendar.
DateTime vs IntlGregorianCalendar:
IntlGregorianCalendar is not better then DateTime. But the good thing about IntlGregorianCalendar is that it will give you the week number as an int.
Example:
$dateTime = new DateTime('21-09-2020 09:00:00');
echo $dateTime->format("W"); // string '39'
$intlCalendar = IntlCalendar::fromDateTime ('21-09-2020 09:00:00');
echo $intlCalendar->get(IntlCalendar::FIELD_WEEK_OF_YEAR); // integer 39
<?php
$ddate = "2012-10-18";
$duedt = explode("-",$ddate);
$date = mktime(0, 0, 0, $duedt[1], $duedt[2],$duedt[0]);
$week = (int)date('W', $date);
echo "Weeknummer: ".$week;
?>
You had the params to mktime wrong - needs to be Month/Day/Year, not Day/Month/Year
To get the week number for a date in North America I do like this:
function week_number($n)
{
$w = date('w', $n);
return 1 + date('z', $n + (6 - $w) * 24 * 3600) / 7;
}
$n = strtotime('2022-12-27');
printf("%s: %d\n", date('D Y-m-d', $n), week_number($n));
and get:
Tue 2022-12-27: 53
for get week number in jalai calendar you can use this:
$weeknumber = date("W"); //number week in year
$dayweek = date("w"); //number day in week
if ($dayweek == "6")
{
$weeknumberint = (int)$weeknumber;
$date2int++;
$weeknumber = (string)$date2int;
}
echo $date2;
result:
15
week number change in saturday
The most of the above given examples create a problem when a year has 53 weeks (like 2020). So every fourth year you will experience a week difference. This code does not:
$thisYear = "2020";
$thisDate = "2020-04-24"; //or any other custom date
$weeknr = date("W", strtotime($thisDate)); //when you want the weeknumber of a specific week, or just enter the weeknumber yourself
$tempDatum = new DateTime();
$tempDatum->setISODate($thisYear, $weeknr);
$tempDatum_start = $tempDatum->format('Y-m-d');
$tempDatum->setISODate($thisYear, $weeknr, 7);
$tempDatum_end = $tempDatum->format('Y-m-d');
echo $tempDatum_start //will output the date of monday
echo $tempDatum_end // will output the date of sunday
Very simple
Just one line:
<?php $date=date("W"); echo "Week " . $date; ?>"
You can also, for example like I needed for a graph, subtract to get the previous week like:
<?php $date=date("W"); echo "Week " . ($date - 1); ?>
Your code will work but you need to flip the 4th and the 5th argument.
I would do it this way
$date_string = "2012-10-18";
$date_int = strtotime($date_string);
$date_date = date($date_int);
$week_number = date('W', $date_date);
echo "Weeknumber: {$week_number}.";
Also, your variable names will be confusing to you after a week of not looking at that code, you should consider reading http://net.tutsplus.com/tutorials/php/why-youre-a-bad-php-programmer/
The rule is that the first week of a year is the week that contains the first Thursday of the year.
I personally use Zend_Date for this kind of calculation and to get the week for today is this simple. They have a lot of other useful functions if you work with dates.
$now = Zend_Date::now();
$week = $now->get(Zend_Date::WEEK);
// 10
To get Correct Week Count for Date 2018-12-31 Please use below Code
$day_count = date('N',strtotime('2018-12-31'));
$week_count = date('W',strtotime('2018-12-31'));
if($week_count=='01' && date('m',strtotime('2018-12-31'))==12){
$yr_count = date('y',strtotime('2018-12-31')) + 1;
}else{
$yr_count = date('y',strtotime('2018-12-31'));
}
function last_monday($date)
{
if (!is_numeric($date))
$date = strtotime($date);
if (date('w', $date) == 1)
return $date;
else
return date('Y-m-d',strtotime('last monday',$date));
}
$date = '2021-01-04'; //Enter custom date
$year = date('Y',strtotime($date));
$date1 = new DateTime($date);
$ldate = last_monday($year."-01-01");
$date2 = new DateTime($ldate);
$diff = $date2->diff($date1)->format("%a");
$diff = $diff/7;
$week = intval($diff) + 1;
echo $week;
//Returns 2.
try this solution
date( 'W', strtotime( "2017-01-01 + 1 day" ) );
Does anyone have a PHP snippet to calculate the next business day for a given date?
How does, for example, YYYY-MM-DD need to be converted to find out the next business day?
Example:
For 03.04.2011 (DD-MM-YYYY) the next business day is 04.04.2011.
For 08.04.2011 the next business day is 11.04.2011.
This is the variable containing the date I need to know the next business day for
$cubeTime['time'];
Variable contains: 2011-04-01
result of the snippet should be: 2011-04-04
Next Weekday
This finds the next weekday from a specific date (not including Saturday or Sunday):
echo date('Y-m-d', strtotime('2011-04-05 +1 Weekday'));
You could also do it with a date variable of course:
$myDate = '2011-04-05';
echo date('Y-m-d', strtotime($myDate . ' +1 Weekday'));
UPDATE: Or, if you have access to PHP's DateTime class (very likely):
$date = new DateTime('2018-01-27');
$date->modify('+7 weekday');
echo $date->format('Y-m-d');
Want to Skip Holidays?:
Although the original poster mentioned "I don't need to consider holidays", if you DO happen to want to ignore holidays, just remember - "Holidays" is just an array of whatever dates you don't want to include and differs by country, region, company, person...etc.
Simply put the above code into a function that excludes/loops past the dates you don't want included. Something like this:
$tmpDate = '2015-06-22';
$holidays = ['2015-07-04', '2015-10-31', '2015-12-25'];
$i = 1;
$nextBusinessDay = date('Y-m-d', strtotime($tmpDate . ' +' . $i . ' Weekday'));
while (in_array($nextBusinessDay, $holidays)) {
$i++;
$nextBusinessDay = date('Y-m-d', strtotime($tmpDate . ' +' . $i . ' Weekday'));
}
I'm sure the above code can be simplified or shortened if you want. I tried to write it in an easy-to-understand way.
For UK holidays you can use
https://www.gov.uk/bank-holidays#england-and-wales
The ICS format data is easy to parse. My suggestion is...
# $date must be in YYYY-MM-DD format
# You can pass in either an array of holidays in YYYYMMDD format
# OR a URL for a .ics file containing holidays
# this defaults to the UK government holiday data for England and Wales
function addBusinessDays($date,$numDays=1,$holidays='') {
if ($holidays==='') $holidays = 'https://www.gov.uk/bank-holidays/england-and-wales.ics';
if (!is_array($holidays)) {
$ch = curl_init($holidays);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$ics = curl_exec($ch);
curl_close($ch);
$ics = explode("\n",$ics);
$ics = preg_grep('/^DTSTART;/',$ics);
$holidays = preg_replace('/^DTSTART;VALUE=DATE:(\\d{4})(\\d{2})(\\d{2}).*/s','$1-$2-$3',$ics);
}
$addDay = 0;
while ($numDays--) {
while (true) {
$addDay++;
$newDate = date('Y-m-d', strtotime("$date +$addDay Days"));
$newDayOfWeek = date('w', strtotime($newDate));
if ( $newDayOfWeek>0 && $newDayOfWeek<6 && !in_array($newDate,$holidays)) break;
}
}
return $newDate;
}
function next_business_day($date) {
$add_day = 0;
do {
$add_day++;
$new_date = date('Y-m-d', strtotime("$date +$add_day Days"));
$new_day_of_week = date('w', strtotime($new_date));
} while($new_day_of_week == 6 || $new_day_of_week == 0);
return $new_date;
}
This function should ignore weekends (6 = Saturday and 0 = Sunday).
This function will calculate the business day in the future or past. Arguments are number of days, forward (1) or backwards(0), and a date. If no date is supplied todays date will be used:
// returned $date Y/m/d
function work_days_from_date($days, $forward, $date=NULL)
{
if(!$date)
{
$date = date('Y-m-d'); // if no date given, use todays date
}
while ($days != 0)
{
$forward == 1 ? $day = strtotime($date.' +1 day') : $day = strtotime($date.' -1 day');
$date = date('Y-m-d',$day);
if( date('N', strtotime($date)) <= 5) // if it's a weekday
{
$days--;
}
}
return $date;
}
What you need to do is:
Convert the provided date into a timestamp.
Use this along with the or w or N formatters for PHP's date command to tell you what day of the week it is.
If it isn't a "business day", you can then increment the timestamp by a day (86400 seconds) and check again until you hit a business day.
N.B.: For this is really work, you'd also need to exclude any bank or public holidays, etc.
I stumbled apon this thread when I was working on a Danish website where I needed to code a "Next day delivery" PHP script.
Here is what I came up with (This will display the name of the next working day in Danish, and the next working + 1 if current time is more than a given limit)
$day["Mon"] = "Mandag";
$day["Tue"] = "Tirsdag";
$day["Wed"] = "Onsdag";
$day["Thu"] = "Torsdag";
$day["Fri"] = "Fredag";
$day["Sat"] = "Lørdag";
$day["Sun"] = "Søndag";
date_default_timezone_set('Europe/Copenhagen');
$date = date('l');
$checkTime = '1400';
$date2 = date(strtotime($date.' +1 Weekday'));
if( date( 'Hi' ) >= $checkTime) {
$date2 = date(strtotime($date.' +2 Weekday'));
}
if (date('l') == 'Saturday'){
$date2 = date(strtotime($date.' +2 Weekday'));
}
if (date('l') == 'Sunday') {
$date2 = date(strtotime($date.' +2 Weekday'));
}
echo '<p>Næste levering: <span>'.$day[date("D", $date2)].'</span></p>';
As you can see in the sample code $checkTime is where I set the time limit which determines if the next day delivery will be +1 working day or +2 working days.
'1400' = 14:00 hours
I know that the if statements can be made more compressed, but I show my code for people to easily understand the way it works.
I hope someone out there can use this little snippet.
Here is the best way to get business days (Mon-Fri) in PHP.
function days()
{
$week=array();
$weekday=["Monday","Tuesday","Wednesday","Thursday","Friday"];
foreach ($weekday as $key => $value)
{
$sort=$value." this week";
$day=date('D', strtotime($sort));
$date=date('d', strtotime($sort));
$year=date('Y-m-d', strtotime($sort));
$weeks['day']= $day;
$weeks['date']= $date;
$weeks['year']= $year;
$week[]=$weeks;
}
return $week;
}
Hope this will help you guys.
Thanks,.
See the example below:
$startDate = new DateTime( '2013-04-01' ); //intialize start date
$endDate = new DateTime( '2013-04-30' ); //initialize end date
$holiday = array('2013-04-11','2013-04-25'); //this is assumed list of holiday
$interval = new DateInterval('P1D'); // set the interval as 1 day
$daterange = new DatePeriod($startDate, $interval ,$endDate);
foreach($daterange as $date){
if($date->format("N") <6 AND !in_array($date->format("Y-m-d"),$holiday))
$result[] = $date->format("Y-m-d");
}
echo "<pre>";print_r($result);

You could do something like this.
/**
* #param string $date
* #param DateTimeZone|null|null $DateTimeZone
* #return \NavigableDate\NavigableDateInterface
*/
function getNextBusinessDay(string $date, ? DateTimeZone $DateTimeZone = null):\NavigableDate\NavigableDateInterface
{
$Date = \NavigableDate\NavigableDateFacade::create($date, $DateTimeZone);
$NextDay = $Date->nextDay();
while(true)
{
$nextDayIndexInTheWeek = (int) $NextDay->format('N');
// check if the day is between Monday and Friday. In DateTime class php, Monday is 1 and Friday is 5
if ($nextDayIndexInTheWeek >= 1 && $nextDayIndexInTheWeek <= 5)
{
break;
}
$NextDay = $NextDay->nextDay();
}
return $NextDay;
}
$date = '2017-02-24';
$NextBussinessDay = getNextBusinessDay($date);
var_dump($NextBussinessDay->format('Y-m-d'));
Output:
string(10) "2017-02-27"
\NavigableDate\NavigableDateFacade::create($date, $DateTimeZone), is provided by php library available at https://packagist.org/packages/ishworkh/navigable-date. You need to first include this library in your project with composer or direct download.
I used below methods in PHP, strtotime() does not work specially in leap year February month.
public static function nextWorkingDay($date, $addDays = 1)
{
if (strlen(trim($date)) <= 10) {
$date = trim($date)." 09:00:00";
}
$date = new DateTime($date);
//Add days
$date->add(new DateInterval('P'.$addDays.'D'));
while ($date->format('N') >= 5)
{
$date->add(new DateInterval('P1D'));
}
return $date->format('Y-m-d H:i:s');
}
This solution for 5 working days (you can change if you required for 6 or 4 days working). if you want to exclude more days like holidays then just check another condition in while loop.
//
while ($date->format('N') >= 5 && !in_array($date->format('Y-m-d'), self::holidayArray()))
