I belive it has being very common to calculate dates based on 1900 01 01 of which the result above is the day before. Years come with leap days and some centuries turn over without a leap day. As a result to be accurate over a long period is quite involved.
Try any date except 0, perhaps 00010000 and see what happens. Zero is famous for divide by zero errors and perhaps year zero never existed. Calendars are supprisingly complex.
