Perpetual Calendar
Basic Description

animated intro
This is an amazing calendar that remains functional for thousands of years. We have three versions: the first is an online version intended for online viewing and printing of selected pages. The year-at-a-glance version uses fourteen ordinary sheets of paper and extends from the year 1600 to 10000. Our favorite is the monthly version that spans 2800 years and fits on 28 sheets of paper. If you used traditional wall calendars during that period, you would need at least 30,000 sheets of paper! Don't worry these aren't microscopic: the pages are full-size.

Next, you need to learn how to use the calendars.
The year at a glance calendar is quite easy to use. Each calendar has a letter key on the back ranging from A to N. Simply find the year in question on the reverse of the calendars to find which letter a given year is associated with. The year 2000, for example is associated with calendar N, so the appropriate yearly calendar for the year 2000 is on the reverse of the page with the letter N.
The monthly perpetual calendar is equally easy to use. The months are keyed with numbers instead of letters from 1 to 28. Find the year that you are interested in and locate the number associated with the month in question. For example, January of the year 2000 is associated with calendar number 7; therefore the reverse side represents January 2000.
