My view...

$strDate = '02/23/2008';
//
$intDate = strtotime($strDate);
$numDaysInMonth = date('t', $intDate);
$dayOfWeek = date('w', $intDate);
$dayOfMonth = date('j', $intDate);
If ($dayOfWeek == 5 && $numDaysInMonth - $dayOfMonth < 7) {
echo "Friday Party!";
} else {
echo "Sorry dude, you missed it";
}

Btw, read the manual (and don't think to be so lucky to not found any bugs in my
code).

$month = 3;
$year = 2008;

for ($day = 31; $day >= 21; $day--) { // maximum of 7 days, but
february starts at 28

$tmp_time = mktime(0, 0, 0, $month, $day, $year);

if (date('w', $tmp_time) === '5') { // 5 = friday

return date('d-m-Y', $tmp_time);
// return $day.'-'.$month.'-'.$year; // without the function
it is faster off course
// echo 'Yeah, friday!';
}
}

Something similar worked for me to find out when daylight saving time is.

Work backwards from the 28th subtracting 86400 from your Unix timestamp
until you get to a Friday. Compare this with your variable.

Eric:

When I read that, I went "Na, that can't be right" -- so I checked it.

You were right -- here it is:

There are plenty of ways. Here's a couple:

OS X:
1. Finder > Applications > iCal (or Command-space for Spotlight, and
then type 'ical')
2. Click on Month (if not already selected)
3. Scroll to February
4. Look

Windows:
1. Double-click the clock in the task bar
2. Scroll to February
3. Look

HTH,
~Philip

PS... For a programmatic way, consult the PHP date functions...

Can't forget *nix:

1. Open a terminal and type the following
%> cal 2 2008

Hi Tedd,

Thanks for the writeup! You could streamline that a bit by using
getdate() and using the returned array values.

Streamline?

Anyway that does the job that I can understand works for me. :-)

that affect -- it's been a long time since I programmed in Perl.
