    I created this function a while ago and needed it again recently, so had to trawl through some old files to find it. Thought I'd post it here in case anyone else finds it useful.

    <?php

    * USAGE:

    *
    * ARGUMENTS
    *
    * $yr = 4 digit numeric representation of the year (eg 1997).
    *
    * RETURN VALUE
    *
    * Returns an array of strings where each string is a date of a bank holiday in the format "yyyy-mm-dd".

    .
    function HijriToGregorian($m, $d, $y)
    {
    //// jd_to_cal -> It Should Be -> cal_to_jd
    return jd_to_cal(CAL_GREGORIAN, HijriCalendar::HijriToJD($m, $d, $y));

    Had a similar problem as curlee, except I needed to create a JDE_ERP date. [format is CYYDDD]

    <?php

    function jde_date_create($month, $day, $year){
    /*
    * NOTE: $month and $day CANNOT have leading zeroes,
    * $year must be'YYYY' format
    */
    $jde_year_prefix = substr($year, 0, 1) - 1;
    $jde_year_suffix = substr($year, -2);

    //note that valid years for mktime are 1902-2037
    $timestamp = mktime(0,0,0,$month, $day, $year);
    $baseline_timestamp = mktime(0,0,0,1,0,$year);

    $day_count = round(($timestamp - $baseline_timestamp)/86400);
    $day_count_padded = str_pad($day_count,3,"0",STR_PAD_LEFT);

    return (    $jde_year_prefix . $jde_year_suffix . $day_count_padded);

    }

    echo     jde_date_create(6,25,2000);// will return '103176'

    ?>

    This is the egyptian calendar which was the first 365 day calendar on the planet it has no leap year which makes it a little inaccurate but you can work on your own implementation of this code when you like, this is another implementation of the roun floating point code which is a universal code for generating date codec's you can make practically all calendars with this code the $pweight is based on my research on carbon date stamping etc of when egypt epoch or PPO was made, some people argue a few thousand years while other can date egypts epoch being around 30000 years ago!! This is on the basis of tidal marking on statues and momuments when the are was covered in water after construction from sea level rising.
