I couldn't decide where to put this post: history or math. I finally settled on history.

Happy leap day. The Gregorian calendar was decreed by Papal bull in 1582. Many countries didn't adopt it until almost 200 years later and Greece finally adopted it in 1923. There's still some variation about adding in that pesky extra time.

If the Europeans hadn't overwhelmed this continent, we might still be using the Mesoamerican calendar, especially the so-called Long Count. This is a very accurate system which is built on base-20, rather than our base-10. (Now you see why I was tempted to put this in the math section.)

I'd like to see a calendar built on base-e. Tha'td be fun! Remember, e is irrational and transcendental; that makes it even cooler. Just imagine an irrational calendar! (And don't say, "How is that different from the one we have now?")

Mercator, mostly famous as the map dude, is the first to have specifically written about base-e and used the phrase "natural logarithm." Wish he'd been a calendar designer instead of a cartographer.

Irrationally and transcendentally yours til 4 years from now,

Frank
