Recycled Calendars

A noted expert writes about Recycling Calendars.

2009 is almost here, and that means a new calendar. Or, you can just recycle an old calendar. If you think about it, only 14 different calendars exist. January 1 can occur on any of seven days -- but some years are leap years and have an additional day.

He then explains, in masterful prose, how to create an Excel spreadsheet to determine which years have identical calendars.

His conclusion:

You can use any of the following calendars for a 2009 calendar: 1903, 1914, 1925, 1931, 1942, 1953, 1959, 1970, 1981, 1987, or 1998.

I think I will use 1981 the year I was married or possibly 1903.

By the way, if you start saving calendars in 2009, you will have a complete set of 14 different calendars in 2036.
