Week list for the current date in PHP

This post shows two examples of how to find the week list for the current date. Input parameter is date, and the output is date list from Monday till Sunday. First example is done with classic algorithm while second example uses ISO week date format.

// set current date
$date = '04/30/2009';
// parse about any English textual datetime description into a Unix timestamp 
$ts = strtotime($date);
// calculate the number of days since Monday
$dow = date('w', $ts);
$offset = $dow - 1;
if ($offset < 0) {
    $offset = 6;
}
// calculate timestamp for the Monday
$ts = $ts - $offset*86400;
// loop from Monday till Sunday 
for ($i = 0; $i < 7; $i++, $ts += 86400){
	print date("m/d/Y l", $ts) . "\n";
}

And here is second example. Just to note that strtotime in PHP 5.1.4 didn't work with YYYY-Www-D format. After I prepared ISO week date format like YYYYWwwD, problem was gone.

// set current date
$date = '04/30/2009';
// parse about any English textual datetime description into a Unix timestamp 
$ts = strtotime($date);
// find the year (ISO-8601 year number) and the current week
$year = date('o', $ts);
$week = date('W', $ts);
// print week for the current date
for($i = 1; $i <= 7; $i++) {
	// timestamp from ISO week date format
	$ts = strtotime($year.'W'.$week.$i);
	print date("m/d/Y l", $ts) . "\n";
}

Here are some examples of ISO week date format:

  • 01/01/2009 is 2009-W01-4 (2009W014)
  • 12/31/2009 is 2009-W53-4 (2009W534)

Each PHP example will output the following list for the input date 04/30/2009

  • 04/27/2009 Monday
  • 04/28/2009 Tuesday
  • 04/29/2009 Wednesday
  • 04/30/2009 Thursday
  • 05/01/2009 Friday
  • 05/02/2009 Saturday
  • 05/03/2009 Sunday

  1. @hello – This PHP function is used in production for a while and it works smoothly. I would gladly fix the problem if you can give more details. Thanks!

  2. NICE! Thanks this is really handy. I wonder, how would i get this to begin not at monday but at the day it is today and then list the next 6 days.

  3. thanks for giving the logic.it’s really working properly…..
    i got the determine result..

  4. $date = date('m/d/Y');
    $ts = strtotime($date);
    $dow = date('w', $ts);
    $offset = $dow - 1;
    if ($offset < 0) {
        $offset = 6;
    }
    $ts = $ts - $offset*86400;
    for ($i = 0; $i < 7; $i++, $ts += 86400) {
        $data .= date(" d", $ts);
    }
    $pieces = explode(" ", $data);
    
  5. @Dean – This script will return whole week from Monday till Sunday for a given date. If you want to display (say Wednesday) it is enough to define $i=3 and to comment out the for loop. Something like this for the second example:

    $i = 3;
    // print week for the current date
    //for($i = 1; $i< = 7; $i++) {
        // timestamp from ISO week date format
        $ts = strtotime($year.'W'.$week.$i);
        print date("m/d/Y l", $ts) . "\n";
    //}
    
  6. Thanks. What I am trying to do is detect the current date, then display the days and dates for Monday through to Sunday for a timetable. I’m a bit noob. :)

  7. @Dean – OK, here is modified PHP code that will display current week and mark current date.

    $format = 'm/d/Y l';         // set Date format
    $ts = time();                // set current Unix timestamp
    $today = date($format, $ts); // set today
    // find the year (ISO-8601 year number) and the current week
    $year = date('o', $ts);
    $week = date('W', $ts);
    // print week for the current date
    for($i = 1; $i <= 7; $i++) {
        // timestamp from ISO week date format
        $ts = strtotime($year.'W'.$week.$i);
        // set day
        $day = date($format, $ts);
        // test if $day is $today
        if ($day == $today) {
            $flag = ' [today]';
        }
        else {
            $flag = '';
        }
        // display result
        print $day . $flag . "\n";
    }
    

    … and the result will be:

    06/13/2011 Monday
    06/14/2011 Tuesday
    06/15/2011 Wednesday [today]
    06/16/2011 Thursday
    06/17/2011 Friday
    06/18/2011 Saturday
    06/19/2011 Sunday

  10. Hi There,

    I am working on a system in wordpress that will only display posts made this week. This post seems to be a starting point. Anyone know what I’d do to say IF today’s date matches any of the dates that are this week? How do I write that in PHP?
