Calculating the third saturday in may?

Black_Hobbit

Is there a way that I can calculate when the third saturday in may is? Or when the first monday in septembers is? Things like that?

I cant test this but maybe

strtotime("3rd Monday of Month");

When I try that I get "-1". That's not what I ment anyway. I wan't very clear:

Lets say I was trying to calculate when Columbus Day (U.S.) was going to be. Columbus Day is the second Monday in October of every year. How can I calculate what day Columbus day will be?

I suspect planetsim's post was meant to be funny.

You can get the day of the week from the date function (0 = sunday):
$dayOfWeek = date('m',mktime(0,0,0,10,1,2004));

Once you know what day of the week the first day of a month is then you can calculate your final date. Wrap it up in a nice function.

You might also look at the PEAR calender class.

PEAR is a bunch of mostly useful classes.

I think what planetsim meant to say was

strtotime('3rd Monday',strtotime('1st May'));

, but ahundiak's approach is likely to be more efficient.

I get a "-1" for that two. I'm getting very confused, but I think it my be something like the following although I've probably made some mistakes. Can anyone impliment this?

//                              fourth monday in january
//          ex                 (04,01,01)                

function find_holiday ($times,$day,$month) {

$year = date("Y");

$dayofweek = day of week the month starts on;

$mydate = mktime(0, 0, 0, $month, 1, $year));

$space = $day + $dayofweek;

$times--;

$mydate = $space + (7 * $times);

return $mydate;

}
