This year, for the first time in 11 years, February begins on Sunday and ends on Saturday. Four perfect full weeks.

I just noticed this.

Looks at desk calendar–weeks start on Sunday.  
Gets up, looks at calendar on side of cabinet–weeks start on Sunday.  
Goes to Big Boss’s office, looks at wall calendar–weeks start on Sunday.

What the hell type of calendars are you looking at?

[ISO 8601](http://en.wikipedia.org/wiki/ISO_8601) - weeks start on Monday  
The US, of course, still uses the ANSI standard.  
The important part is two paydays, Feb. 2012 will have three paydays for me. 🙂
