Easter is one of the most difficult holidays to calculate. Several years ago, a Web site had a contest to see who could come up with the best formula to calculate the date of Easter for any year. Here's one of the formulas submitted (it assumes that cell A1 contains a year):
Just for fun, I calculated the date of Easter for 300 years from 1900 through 2199. Then I created a pivot table, and grouped the dates by day. And then, a pivot chart:
During this 300-year period, the most common date for Easter is March 31 (it
occurs 13 times on that data). The least common is March 24 (only one
occurrence). I also learned that the next time Easter falls on April Fool's Day
will be in 2018.
Excel has a long history, and it continues to evolve and change. Consequently, the tips provided here do not necessarily apply to all versions of Excel.
In particular, the user interface for Excel 2007 (and later), is vastly different from its predecessors. Therefore, the menu commands listed in older tips, will not correspond to the Excel 2007 (and later) user interface.
