Works for me:
derick@kossu:~$ php
<?php
echo date("w",mktime(0,0,0,12,01,1933));

?>
5

derick@kossu:~$ php -v

Which timezone is listed in phpinfo() output and what does "echo date_default_timezone_get();" output?
 [2006-12-27 14:29 UTC] testingthis222 at hotmail dot com 
I'm sorry I seem to have posted it in the wrong version-thread.

My php version is 4.4.4.

echo date("w",mktime(0,0,0,12,01,1933));

returns 3 while it should be 5

(shouldn't it be 5 regardless of timezone?)

anyway; phpinfo() has no default TZ listed; and changing it to a US timezone doesn't change the output (still returns 3)


echo date_default_timezone_get();

seems to not be available in version 4.4.4.

should have used

$is_day=jddayofweek(cal_to_jd(CAL_GREGORIAN,$month,$day,$year),0)+1;

to dates prior to 1970 in version 4.4.4.
