The Perpetual Calendar spreadsheet started out as an ordinary spreadsheet, formatted as a calendar. Each year I would make a new version for that year. But that got old. Finally, I decided to make one that would work for any year.
To use it, just type the year in Cell A1. The spreadsheet will automatically show the calendar for that year. This works for any year A. D., from 1 to approximately 50,000,000,000. For those of you who care about such things, this spreadsheet follows the British calendar, which changed from Julian to Gregorian in 1752.
