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.

yes interesting..28 mostly sometimes 12 or 40 yrs for selected leap years ..while commonly =11yrs and about halftimes =6yrs for non-leap years..
Each month suppose to have 7 templates ;day 1on MTWTFSS except 14 templates for February for day 29 /LYR
then.. the equation is difficult i think the repeating calendar calculator link will do.. Thanks much

I believe this is what you are looking for; http://en.wikipedia.org/wiki/Perpetual_calendar
I read about these years ago, just remembered it now.
