Watch out for the Calendar Geeks

Rejoice Calendar Geeks. There are fewer of us even than those who really understand Haskell monads. It's obvious that the Java/Calendar classes were implemented by people who were not calendar geeks. (I once implemented a date package that was usable from 4000BC to several thousand years in the future by porting some HP-48 code.)<p>Best of all for me, this July has 3 paydays.

The same co-worker has a Lucite perpetual calendar on his desk. I asked him how many different calendar options it had.<p>"Seven."<p>"Doesn't it beggar belief that one of those seven would only get used once every 800 years?"

I'm no calendar geek. I have however written production software that had to do date calculations, so wound up having to do the whole Gregorian to Julian and back conversion thing.<p>I was doing this before they wrote the book on it: <a href="http://www.calendarists.com" rel="nofollow">http://www.calendarists.com</a>
