RE: [PHP-WIN] Help with Calendar Functions!!

Thanks for the insight to the Octal issue. What do I do with the -4713 number? How do I get the Julian Day from 11/9/2000 using these functions? Does it not work with windows? Thanks in advance. -----Original Message----- From: Zak Greant [mailto:zak@php.net] Sent: Friday, November 10, 2000 9:44 AM To: Joey Garcia Cc: php-windows@lists.php.net Subject: Re: [PHP-WIN] Help with Calendar Functions!!

Because 09 is an invalid octal number, 0 is substituted for it. >Also, I got weird results with the JD2Julian function > >$temp=jdtojulian(301); >print $temp; > >I got the result of 10/28/-4713 That's right JDs start in 4713 BC - BS is indicated with a leading -. --zak
