 Suppose i had an old calendar and wanted to reuse it by changing its year in the future. Is there some equation i can apply or pattern to follow so that i can know when my old calendar is useful again? The best i can do is just browsing on my computers [Date and Time Properties] to see if it match.

 I think it's usually about 28 years, but there are exceptions due to leap years. I am not aware of any equations, but that doesn't mean they don't exist.http://www.timeanddate.com/calendar/repeating.html _________________iNow"[Time] is one of those concepts that is profoundly resistant to a simple definition." ~C.

 I believe this is what you are looking for; http://en.wikipedia.org/wiki/Perpetual_calendarI read about these years ago, just remembered it now. _________________It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence.-W. K. Clifford-
