I recently had to write a function that allows me to know if today is a holiday.And in France, we have some holidays which depends on the easter date. Maybe this will be helpful to someone.Just modify in the $holidays array the actual holidays dates of your country.<?phpprotected static function getHolidays($year = null){ if ($year === null) { $year = intval(date('Y')); } $easterDate = easter_date($year); $easterDay = date('j', $easterDate); $easterMonth = date('n', $easterDate); $easterYear = date('Y', $easterDate); $holidays = array( mktime(0, 0, 0, 1, 1, $year), mktime(0, 0, 0, 5, 1, $year), mktime(0, 0, 0, 5, 8, $year), mktime(0, 0, 0, 7, 14, $year), mktime(0, 0, 0, 8, 15, $year), mktime(0, 0, 0, 11, 1, $year), mktime(0, 0, 0, 11, 11, $year), mktime(0, 0, 0, 12, 25, $year), mktime(0, 0, 0, $easterMonth, $easterDay + 2, $easterYear), mktime(0, 0, 0, $easterMonth, $easterDay + 40, $easterYear), mktime(0, 0, 0, $easterMonth, $easterDay + 50, $easterYear), ); sort($holidays); return $holidays;}?>
