PHP cal_from_jd Function: Convert Julian Day to a Supported Calendar

The cal_from_jd() function converts a Julian Day number ( $jd) into a date based on the chosen calendar ( $calendar). Supported calendar constants are CAL_GREGORIAN, CAL_JULIAN, CAL_JEWISH, and CAL_FRENCH.

Parameters

jd : an integer representing the Julian Day count.

calendar : the calendar constant to which the date should be converted.

Return value

The function returns an associative array containing the date components: month, day, year, day of week (both numeric and textual forms), and month names (both abbreviated and full). The date format in the array is "month/day/year".

Example usage

<?php
$today = unixtojd(mktime(0,0,0,8,16,2003));
print_r(cal_from_jd($today, CAL_GREGORIAN));
?>
