I was using the following code for some months now without any issue in order to get the current week start/end date (Monday/Sunday):
date_default_timezone_set('Europe/Bucharest'); //this is the default in php.ini
$monday = strtotime('next Monday -1 week');
$monday = date('w', $monday)==date('w') ? $monday+7*86400 : $monday;
$sunday = strtotime(date("Y-m-d",$monday)." +6 days");
echo "Current week start/end date:<br>";
echo $this_week_sd = date("Y-m-d",$monday)."<br>";
echo $this_week_ed = date("Y-m-d",$sunday)."<br>";
//Expected result:
2018-10-29
2018-11-04
However, as of Today this for some reason has been offset by 1 day:
//Actual incorrect result:
2018-10-28
2018-11-03
Then I remembered that Yesterday the clock went back 1 hour due to DST, so I decided to change the timezone from Europe/Bucharest to Europe/Istanbul which still has a +3 hours advance against GMT:
date_default_timezone_set('Europe/Istanbul');
//Now the result is correct:
2018-10-29
2018-11-04
Question is, how can I offset DST in the current code so that I could keep the relative week dates in accordance with Europe/Bucharest timezone? Any pointers or explanations would be appreciated. Thank you.
If you just want to fix your current Code, just replace your three "ugly" ;-) lines:
$monday = strtotime('next Monday -1 week');
$monday = date('w', $monday)==date('w') ? strtotime(date("Y-m-d",$monday)." +7 days") : $monday;
$sunday = strtotime(date("Y-m-d",$monday)." +6 days");
with those "nice" one, and it will work.
$monday = strtotime('monday this week');
$sunday = strtotime('sunday this week');
PHPs relative Date Expressions can handle this nice.
I would do this using the DateTime class and keep everything in UTC so you never have to worry about daylight savings time:
$today = new DateTime('now', new DateTimeZone('UTC'));
$day_of_week = $today->format('w');
$today->modify('- ' . (($day_of_week - 1 + 7) % 7) . 'days');
$sunday = clone $today;
$sunday->modify('+ 6 days');
echo $today->format('Y-m-d') . "\n";
echo $sunday->format('Y-m-d');
Output:
2018-10-29
2018-11-04

I am aware that there is more than one way to skin a cat, but in this case I was interested in how to fix my current code and more importantly to find out what's wrong with it.
Thank you all for your suggestions, especially to #misorude for pointing out the obvious flaw in my initial code, whereas "not every day has 86400 seconds", which is especially true during DST.
So here's the updated working code using relative "days" instead of fixed seconds amount:
$monday = strtotime('next Monday -1 week');
$monday = date('w', $monday)==date('w') ? strtotime(date("Y-m-d",$monday)." +7 days") : $monday;
$sunday = strtotime(date("Y-m-d",$monday)." +6 days");
echo "This week start/end date:<br>";
echo $this_week_sd = date("Y-m-d",$monday)."<br>";
echo $this_week_ed = date("Y-m-d",$sunday)."<br>";
//output:
This week start/end date:
2018-10-29
2018-11-04
Once again, thank you all for your inputs. Much appreciated!
I need to get the next month with php. Everywhere is written these example
date('Y-m-t', strtotime('+1 month'));
The output of the above code is '2017-03-31'. I need to get February, not March.
If you want to get the next irrespective of the current date in the current month. below code may help you
echo date('M',strtotime('first day of +1 month'));
// e.g. "Jan"
echo date('m',strtotime('first day of +1 month'));
// e.g. "1"
echo date('F',strtotime('first day of +1 month'));
// e.g. "January"
This will give you Next month.
You can find more formatting masks in date() function documentation
Use Like This
// One month from today
$date = date('Y-m-d', strtotime('+1 month'));
// One month from a specific date
$date = date('Y-m-d', strtotime('+1 month', strtotime('2015-01-01')));
To get next month using php use string to time function as below:
$nxtm = strtotime("next month");
echo date("M", $nxtm);
date("m", strtotime("2021-08-16 +1 Month"));
You can use the code below to get the next months first day.
$date = (new \DateTime('first day of next month'))->format('Y-m-d');
This is safer than 'next month' or '+1 month' because you may skip some months then.
If you want to have the next month with the same day as this month, or the last day of the next month if it otherwise would switch month you can use this function
function nextMonth()
{
$nextMonthNumber = date('M', strtotime('first day of +1 month'));
$nextMonthDate = new DateTime();
$nextMonthDate->add(new DateInterval('P1M'));
while ($nextMonthDate->format('M') != $nextMonthNumber) {
$nextMonthDate->sub(new DateInterval('P1D'));
}
return $nextMonthDate;
}
How can i get a Date of Monday and Date of Sunday if i have specific Date in mysql DATETIME format ?
i am trying to get the week's first day's date and last day's date in which the given date falls.
i have date '2016-06-05' its in 'Y-m-d'
and i am trying it like this way.
<?php
$date = '2016-06-05';
echo date("Y-m-d", strtotime('monday this week', strtotime($date))), "\n";
echo date("Y-m-d", strtotime('sunday this week', strtotime($date))), "\n";
?>
but its giving
2016-06-06
2016-06-12
which is wrong week, it should give
2016-05-30
2016-06-05
i even tried like this way.
$date = '2016-06-05';
echo date("Y-m-d", strtotime('monday', strtotime('this week', strtotime($date)))), "\n";
echo date("Y-m-d", strtotime('sunday', strtotime('this week', strtotime($date)))), "\n";
OR
$date = '2016-06-05';
echo date("Y-m-d", strtotime('monday', strtotime($date))), "\n";
echo date("Y-m-d", strtotime('sunday', strtotime($date))), "\n";
using PHP 5.3
what am i missing here ?
UPDATE:
i came up with this, this is giving expected output.
function get_monday_sunday($date){
$dates_array = array();
if(date('N', strtotime($date)) == 7){
$dates_array['monday'] = date("Y-m-d", strtotime('Monday last week', strtotime($date)));
$dates_array['sunday'] = date("Y-m-d", strtotime('Sunday last week', strtotime($date)));
}else{
$dates_array['monday'] = date("Y-m-d", strtotime('Monday this week', strtotime($date)));
$dates_array['sunday'] = date("Y-m-d", strtotime('Sunday this week', strtotime($date)));
}
return $dates_array;
}
$date = '2016-06-05'
print_r(get_monday_sunday($date));
looks like when the day is last day of week, then next week starts over, i.e. php week start is sunday i guess.
In every single php project I make, I always include the Carbon package. It extends the DateTime class and adds some very nice functionality that makes working with dates a lot easier.
If you would take my suggestion, your code would look something like this:
$date = Carbon::parse($dateStringFromDb);
echo $date->startOfWeek()->format('Y-m-d'); // monday
echo $date->endOfWeek()->format('Y-m-d'); // sunday
And that is really all there is to it. This is what I call "self commenting code"! I bet you're actually going to enjoy program with dates ;-)
Here's a summary of the issue: On Sundays, strtotime('this week') returns the start of next week.
In PHP, the week seems to start on Monday. But, on any day except Sunday, this code
echo date('Y-m-d', strtotime('monday this week', strtotime('last sunday')));
Outputs the date of this week's Monday, when it seems like it should be outputting last weeks Monday. It seems like, in this case, PHP is treating both Sunday and Monday as the the start of the week. It's now Monday, Dec 10, 2012, or 2012-12-10. date('Y-m-d', strtotime('sunday last week')) returns 2012-12-09 - yesterday.
Is this a bug, or am I missing something? It seems like a bug this obvious should be fairly well known, but I can't find anything about it. Is the only way to get the start of the week to use some special handling for Sundays?
$week_offset = (int) 'sunday' == date('l');
$week_start = strtotime("-$week_offset monday"); // 1 or 0 Mondays ago
As far as I can tell, this is a bug. I see no logical reason why strtotime('this week'); should return a future date. This is a pretty major bug. In my particular case, I had a leaderboard that showed the users with the most points since the beginning of the week. But on Sundays, it was empty because strtotime returned a timestamp for a future date. I was doubtful, because just I don't know how this could have gone unnoticed, but I couldn't find any other reports of this bug.
Thanks for all your time and help, folks.
This answer is late, but it's something that I've been struggling with. Every solution I've tried so far has malfunctioned for one reason or another. This is what I ended up with that worked for me. (though it may be look pretty, it at least works).
$thisMonday = strtotime('next Monday -1 week', strtotime('this sunday'));
Here is how you can get Monday of current week:
echo date("Y-m-d", strtotime(date('o-\\WW')));
It's not ideal but this is what I resorted to using:
if(date('N') == 7) {
$date = date('Y-m-d',strtotime('monday last week'));
} else {
$date = date('Y-m-d',strtotime('monday this week'));
}
I think the only problem with your coding is TimeZone.
Solution:
Set your own time Zone. Here is the example of my own time zone:
Example
date_default_timezone_set('Asia/Kolkata');
Set the above line before calling any time function.
Have a nice day.
I think instead of trying
echo date('Y-m-d', strtotime('monday this week', strtotime('last sunday')));
you should try
echo date('Y-m-d', strtotime('monday last week'));
Try this code
// set current date
$date = date("m/d/Y");
$ts = strtotime($date); // also $ts = time();
// find the year and the current week
$year = date('o', $ts);
$week = date('W', $ts);
// print week for the current date
$i = 1; // 1 denotes the first day of week
$ts = strtotime($year.'W'.$week.$i);
echo $day = date("l", $ts); // generate the name of day
echo "<br>";
echo $day = date("Y-m-d", $ts); // generate the date
You will get the the date of current week, whether you are on monday you will get the date of that monday.
If you want the most recent monday:
function mostRecentMonday(){
if(date("w") == 1){
return strtotime("midnight today");
} else {
return strtotime("last monday");
}
}
Easy to modify to use DateTime, or, to even specify a different date to use as the base.
Based on Bryant answer :
$first_week_date = date('d F Y', strtotime('next Monday -1 week', strtotime('this sunday')));
$last_week_date = date('d F Y', strtotime('next Monday -1 week + 6 days', strtotime('this sunday')));
This is for thos looking for a friendly solution that works with any day.
function getWeekStart($week_start_day = "Monday") {
$week_days = array("Sunday"=>0,"Monday"=>1,"Tuesday"=>2,"Wednesday"=>3,"Thursday"=>4,"Friday"=>5,"Saturday"=>6,);
if(!isset($week_days[$week_start_day])) {
return false;
} else {
$start_day = $week_days[$week_start_day];
$today = date("w");
$one_day = (60 * 60 * 24);
if($today < $start_day) {
$days_difference = 7 - ($start_day - $today);
} else {
$days_difference = ($today - $start_day);
}
$week_starts = strtotime(date("Y-m-d 00:00:00")) - ($one_day * $days_difference);
return $week_starts;
}
}
//Test: If today is Monday, it will return today's date
echo date("Y-m-d H:i:s", getWeekStart("Monday"));
I can get the Monday of this week with:
$monday = date_create()->modify('this Monday');
I would like to get with the same ease the 1st of this month. How can I achieve that?
Here is what I use.
First day of the month:
date('Y-m-01');
Last day of the month:
date('Y-m-t');
Requires PHP 5.3 to work ("first day of" is introduced in PHP 5.3). Otherwise the example above is the only way to do it:
<?php
// First day of this month
$d = new DateTime('first day of this month');
echo $d->format('jS, F Y');
// First day of a specific month
$d = new DateTime('2010-01-19');
$d->modify('first day of this month');
echo $d->format('jS, F Y');
// alternatively...
echo date_create('2010-01-19')
->modify('first day of this month')
->format('jS, F Y');
In PHP 5.4+ you can do this:
<?php
// First day of this month
echo (new DateTime('first day of this month'))->format('jS, F Y');
echo (new DateTime('2010-01-19'))
->modify('first day of this month')
->format('jS, F Y');
If you prefer a concise way to do this, and already have the year and month in numerical values, you can use date():
<?php
echo date('Y-m-01'); // first day of this month
echo "$year-$month-01"; // first day of a month chosen by you
This is everything you need:
$week_start = strtotime('last Sunday', time());
$week_end = strtotime('next Sunday', time());
$month_start = strtotime('first day of this month', time());
$month_end = strtotime('last day of this month', time());
$year_start = strtotime('first day of January', time());
$year_end = strtotime('last day of December', time());
echo date('D, M jS Y', $week_start).'<br/>';
echo date('D, M jS Y', $week_end).'<br/>';
echo date('D, M jS Y', $month_start).'<br/>';
echo date('D, M jS Y', $month_end).'<br/>';
echo date('D, M jS Y', $year_start).'<br/>';
echo date('D, M jS Y', $year_end).'<br/>';
Currently I'm using this solution:
$firstDay = new \DateTime('first day of this month');
$lastDay = new \DateTime('last day of this month');
The only issue I came upon is that strange time is being set. I needed correct range for our search interface and I ended up with this:
$firstDay = new \DateTime('first day of this month 00:00:00');
$lastDay = new \DateTime('first day of next month 00:00:00');
I use a crazy way to do this is using this command
$firstDay=date('Y-m-d',strtotime("first day of this month"));
$lastDay=date('Y-m-d',strtotime("last day of this month"));
Thats all
In php 5.2 you can use:
<? $d = date_create();
print date_create($d->format('Y-m-1'))->format('Y-m-d') ?>
Ugly, (and doesn't use your method call above) but works:
echo 'First day of the month: ' . date('m/d/y h:i a',(strtotime('this month',strtotime(date('m/01/y')))));
You can do it like this:
$firstday = date_create()->modify('first day January 2010');
using date method, we should be able to get the result.
ie; date('N/D/l', mktime(0, 0, 0, month, day, year));
For Example
echo date('N', mktime(0, 0, 0, 7, 1, 2017)); // will return 6
echo date('D', mktime(0, 0, 0, 7, 1, 2017)); // will return Sat
echo date('l', mktime(0, 0, 0, 7, 1, 2017)); // will return Saturday
I use this with a daily cron job to check if I should send an email on the first day of any given month to my affiliates. It's a few more lines than the other answers but solid as a rock.
//is this the first day of the month?
$date = date('Y-m-d');
$pieces = explode("-", $date);
$day = $pieces[2];
//if it's not the first day then stop
if($day != "01") {
echo "error - it's not the first of the month today";
exit;
}
Timestamp for start of this month and very last second of current month.
You can add 00:00:00 or just reference "today"
Alternative:
$startOfThisMonth = strtotime("first day of this month",strtotime("today"));
OR
$startOfThisMonth = strtotime("first day of this month 00:00:00");
$endOfThisMonth = strtotime("first day of next month",$startOfThisMonth)-1;
I am providing this answer as an alternative one liner if the DateTime object is not preferred
Basically, I get the current day number, reduce it by one then take that number of days from itself ("today" which automatically resets the clock to 00:00:00 too) and you get the start of the month.
$startOfMonth = strtotime("today - ".(date("j")-1)." days");
If you're using composer, you can install carbon:
composer require nesbot/carbon
This is then as simple as:
use Carbon/Carbon;
$startOfMonth = Carbon::now()->startOfMonth()->toDateTime();
