Date.prototype.getJulian = function() {
return Math.floor((this / 86400000) -
(this.getTimezoneOffset()/60000) + 2440587.5);
}
var [b]julianDay[/b]=new Date([b]year[/b],0,[b]day[/b]).getJulian();

just substitute the year and day from the julian dddyyyy in as year and day and the correct julian day will be returned in julianDay.

@AgilysysLarryauthorJan 11.2007 — Thanks everyone. I got it. We convereted the date server side to true Julian from the mmddyyyy and sent it to the page.

I really tried to avoid that church debate with what I thought was a well phrased question about a conversion utility. :-/
