Anyone feeling extra geeky today? Well you should. Today's date, when written in a six digit format (MMDDYY), is a binary style number. Updated.

Writes reader Eric, who tipped us off about the date earlier this morning:

It just occurred to me that today's six digit date format (MMDDYY or YYMMDD) is in binary style. Thought this was interesting and wanted to share it with the Gizmodo team. From what I can tell, this looks like it will be the only year it happens and will happen four times (January 1st and 10th and October 1st and 10th).

As you can see, this neat little phenomenon will happen a few more times throughout this year and next. 2010: Geekiest year ever? Update: As noted below, "Oct. 10th 2011 November 11, 2011 will be the last binary day of this century."
