Re: Last Sunday in September?

There's going to be 'tighter' and more efficient ways to do this.. probably some using strtotime().  I have an irrational distrust of the results from strtotime() though, so I use it sparingly.

Here's a simple solution though:

<?php
  // Designate month
  $month = "2";
  // Designate year
  $year = "2006";
  // Find last day of the month by finding how many days are in month
  // Could also do $month + 1, $day = 0
  $lastday = date("t", mktime(0, 0, 0, $month, 1, $year));
  // Find out what numerical day of the week it is, 0 = sunday, 6 = saturday
  $dayofweek = date("w", mktime(0, 0, 0, $month, $lastday, $year));
  // Subtract day of week from current day.  If you're already on last
  // sunday of the month, it'll be $lastday - 0 so it all works out
  $lastsunday = date("Y-m-d", mktime(0, 0, 0, $month, $lastday - $dayofweek, $year));

  echo $lastsunday;
?>

There's going to be a dozen ways to skin this one, just showing one way.

Hi,

I'm building a program and I need to find the last Sunday in September for
every year because the following Monday is the start of a new year for us.
So 2006 ends on September 24th 2006 and the new year (2007) starts on
September 25th 2006.  I was thinking that using the strtotime() would get me
this information possibly?  Is there an easy way to get this information?

Pseudo code:

If ((date > last Sunday in September this year) &&
    (date < Jan 1 of next year)) 
    year++
