JohnOne 1,589 Posted September 26, 2010 You how you always need to check if its easter sunday on a certain date in a couple of years. ConsoleWrite(_IsEasterSunday(31,3,2013) & @LF); d m yyyy Func _IsEasterSunday($iday, $imonth, $iyear) If $iyear < 1 Or $iyear > 9999 Then Return False Exit EndIf $a = Mod($iyear, 19) $b = Mod($iyear, 4) $c = Mod($iyear, 7) $d = Mod(19 * $a + 24, 30) $e = Mod(2 * $b + 4 * $c + 6 * $d + 5, 7) $sunday = 22 + $d + $e $month = 3 If $sunday > 31 Then $month = 4 $sunday -= 31 EndIf If $iday = $sunday And $imonth = $month Then Return True Else Return False EndIf EndFunc Sorry I couldnt find on on the forum.

czardas 1,175 Posted September 27, 2010 I find it quite annoying when all these dates keep changing. Didn't they try and change St. Patricks day a year ago. I suppose it's one of those social phenomenons. Still it would be useful to have a varied library of international public holiday dates. It would be pretty useful for international stuff. operator64 ArrayWorkshop Share this post Link to post Share on other sites
