Function getDayCountBetweenDates basing on Julian date.

[Mattwell]

Hi, I wrote short day counter between dates basing on Julian date algorithm.

Function returns the difference of days between dates.

USEFUL FOR PREMIUM ACCOUNTS OR ANOTHER THINGS

Code:

function getDayCountBetweenDates(d1d,d1m,d1y,d2d,d2m,d2y)
{
    local date1 = (1461 * (d1y + 4800 + (d1m - 14)/12))/4 + (367 * (d1m - 2 - 12 * ((d1m - 14)/12)))/12 - (3 * ((d1y + 4900 + (d1m - 14)/12)/100))/4 + d1d - 32075;
    
    
    local date2 = (1461 * (d2y + 4800 + (d2m - 14)/12))/4 + (367 * (d2m - 2 - 12 * ((d2m - 14)/12)))/12 - (3 * ((d2y + 4900 + (d2m - 14)/12)/100))/4 + d2d - 32075;
    
    if(date2 > date1)
    {
        return date2 - date1;
    }
    else
    {
        return date1 - date2;
    }
    
}
