Microsoft Project Server 2010 cannot calculate days after December 31, 2049 or before January 1, 1984. The s_max_day value = (Julian date of the maximum project date) – (Julian date of the minimum project date). That is, 2469808 – 2445701 = 24107.
The Julian date is the number of days since January 1, 4713 BC.
