Mind Over Matters

The February 2008 issue of LinuxPro magazine has an entertaining article, Mind Games, by Michael Schilli. In it a mental method of calculating the day of the week for any date from 1700 on is given. Seems the procedure was developed by Lewis Carroll, the author of Alice's Adventures in Wonderland.

I've worked it out several times in my own head, and it's a pretty cool thing altogether. However, I did find that the method actually fails for dates ealier than September 14, 1752. Why, well I'll leave it to you as a check of your own pet Operating Systems. Check out the article, and come back later when I'll post my answer, and you can leave yours here in the meantime.

Cheers :-)
