The Checker Maven

Presidents' Day

20150107-presseal.jpg

We wonder--- how many readers can recall the origin of Presidents' Day?

The older among us will recall the February 22 celebration of Washington's Birthday, and perhaps the February 12 celebration of Lincoln's Birthday in some states such as Illinois. Observation of Washington's Birthday goes back to the 1800s, in fact, becoming a Federal holiday in 1879.

But at some point in the 1960s a movement began for more three-day weekends, and finally in 1971 Washington's Birthday began to officially be observed on the third Monday in February. By the 1980s, the name "Presidents' Day" was in common use.

The holiday is now intended to honor all of our Presidents. And that points out one thing about America: we're all free to like or dislike our President as we see fit--- and be as open as we want about it--- but the Office of the President deserves the greatest of respect.

Today we're featuring a checker problem derived from a book published back in 1886.
