Neither George Washington's birthday (Feb 22) nor Abraham Lincoln's birthday (Feb 12) can fall on the U.S. holiday commonly referred to as President's Day (the third Monday in February). Ironically enough, the official name of the holiday is still George Washington's Birthday!!
Here's something I bet you've never noticed: In any year (even a leap year), July always begins on the same day of the week that April does. Therefore, the only difference between a July calendar page and an April calendar page in the same year (other than the holiday) is the extra day July has. The same relationship exists between September and December as well as between March and November. Add an extra day to the September page and you've got December. Take a day away from the March page and you've got November. In non-leap years only, there are additional matches: October duplicates January, and March and November duplicate February in their first 28 days. In leap years only, there is a different set of additional matches: July is a duplicate of January while February is duplicated in the first 29 days of August.
In 1988, the eventual presidential nominees of the major parties, Michael Dukakis (Democrat) and George H.W. Bush (Republican), both came in third in their party's Iowa Caucuses. It's the only time in history that someone coming in third in the Iowa Caucuses (when they were contested) went on to win his party's presidential nomination.
