Regarding the jewish date system. It may be worth noting the following peculiarities, some obvious some not so.
1. Jewish days start at sunset NOT midnight so when converting from a Gregorian date to a Jewish one it might be worth asking if the date/time occurred 'after sunset'.
2. Jewish leap years follow a 19 year cycle which can be calculated like this:
function isJLeapYear($JYear) {
if ( ((7 * $JYear + 1) % 19) < 7 )
return true;
else
return false;
}
3. During a leap year a new leap-month called "Adar I" is inserted BEFORE the normal month of Adar.
4. During leap years, Adar is renamed "Adar II".
5. Adar/Adar II has 29 days
6. Adar I has 30 days
7. Cheshvan & Kislev have between 29 & 30 Days
8. Leap years have between 383 and 385 days.
8. non-leap years have between 353 and 355 days.
9 . In a 354-day year, months have alternating 30 and 29 day lengths.
10. In a 353-day year, the month of Kislev is reduced to 29 days.
11. In a 355-day year, the month of Cheshvan is increased to 30 days.
12. Leap years years follow the same pattern, with the addition of the 30-day Adar I as well.

Use this function if you prefer to use the standard calendar constants:

<?php function jdmonthname2($julianday, $calendar, $abbrev = false) { if($calendar == CAL_GREGORIAN && $abbrev) $mode = 0; elseif($calendar == CAL_GREGORIAN && !$abbrev) $mode = 1; elseif($calendar == CAL_JULIAN && $abbrev) $mode = 2; elseif($calendar == CAL_JULIAN && !$abbrev) $mode = 3; elseif($calendar == CAL_JEWISH) $mode = 4; elseif($calendar == CAL_FRENCH) $mode = 5; else $mode = 10; //use an invalid mode and let the underlying function handle it return jdmonthname($julianday, $mode); } ?>
