It’s a big week for geeks. Yesterday, the IT guy just told me, was square root day. On 3/3/09, the day and the month were both the square root of the last two digits of the year. (If you missed this one, there’s another one coming up on 4/4/16.)

Today, March 4th, is National Grammar Day. Unclear what the relationship between the date and the holiday is, other than that the website urges you to “march forth,” ostensibly to shout “WHOM!” if somebody asks you “Who are you kidding with this?”

As an added treat, the chief copy editor at the Baltimore Sun has been serializing a “grammar noir” in preparation for the big day.

So shake up a grammartini and remember to talk good.
