note 119905 added to function.cal-to-jd

The earliest supported date in the Julian calendar is January 2, 4713 BC. The corresponding Julian day count is 1. PHP treats -4713 as equal to 4713 BC, and does not allow the year 0; this practice is different than the custom of astronomers, who treat -4712 as equal to 4713 BC. ---- Server IP: 72.52.91.14 Probable Submitter: 2601:197:4000:2c74:e8ca:30cf:7a4b:3f54 ---- Manual Page -- http://php.net/manual/en/function.cal-to-jd.php Edit -- https://master.php.net/note/edit/119905 Del: integrated -- https://master.php.net/note/delete/119905/integrated Del: useless -- https://master.php.net/note/delete/119905/useless Del: bad code -- https://master.php.net/note/delete/119905/bad+code Del: spam -- https://master.php.net/note/delete/119905/spam Del: non-english -- https://master.php.net/note/delete/119905/non-english Del: in docs -- https://master.php.net/note/delete/119905/in+docs Del: other reasons-- https://master.php.net/note/delete/119905 Reject -- https://master.php.net/note/reject/119905 Search -- https://master.php.net/manage/user-notes.php
