note 112424 added to function.jdmonthname

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. ---- Server IP: 69.147.83.199 Probable Submitter: 78.149.255.217 ---- Manual Page -- http://php.net/manual/en/function.jdmonthname.php Edit -- https://master.php.net/note/edit/112424 Del: integrated -- https://master.php.net/note/delete/112424/integrated Del: useless -- https://master.php.net/note/delete/112424/useless Del: bad code -- https://master.php.net/note/delete/112424/bad+code Del: spam -- https://master.php.net/note/delete/112424/spam Del: non-english -- https://master.php.net/note/delete/112424/non-english Del: in docs -- https://master.php.net/note/delete/112424/in+docs Del: other reasons-- https://master.php.net/note/delete/112424 Reject -- https://master.php.net/note/reject/112424 Search -- https://master.php.net/manage/user-notes.php
