Indeed. However, the jdmonthname and jewishtojd man pages have some information about this. > Also, the name "AdarI" is used for Adar in all years, not just > years with 13 months. This has been reported as bug #54254, and fixed as of PHP 5.5.0. Previous Comments: ------------------------------------------------------------------------ [2013-01-07 17:56:58] r07271368 at hotmail dot com Description: ------------ The numbering that cal_from_jd uses for Jewish months is not explained in the documentation. Apparently, the first six months of the Jewish year (counting from Tishri) are numbered 1 to 6; the last six months are numbered 8 to 13; and 7 appears as a month number only if the year has 13 months total. If the year is 12 months in length, then the number 7 is skipped in the month numbering. Also, the name "AdarI" is used for Adar in all years, not just years with 13 months. Test script: --------------- $n = 2456150; for ($i=1; $i<=150; $i++) { $a = cal_from_jd($n, CAL_GREGORIAN); $b = cal_from_jd($n, CAL_JEWISH); echo $a['date']." "; echo $b['date']." "; echo $b['monthname']."\n"; $n+=15; } Expected result: ---------------- The script shows Gregorian and corresponding Jewish dates at 15-day intervals. A Jewish month is either 29 or 30 days. Therefore, the interval is too short to skip over any months. Actual result: -------------- Please observe the sequence of month names and month numbers returned by the script. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63932&edit=1
