Selection of Dates in March 2013 are Off by One

[blakewatters]

Starting on March 11, 2013 the date selection logic is thrown off. Through March 10, tapping on the date cell highlights the appropriate cell. When you try to tap March 11, the 10th stays highlighted. The rest of the month has this off by one error which I expect is related to the 28 day month of February.

I am working on a fix now.
