Retirement Date Calculation?

I primarily bought the app to calculate the dates for my garden harvest. Once I had the app, I tried a sample calculation for my retirement date... When the results were off I tried the web version.

I input my November 2007 start date, 360 months, the results were both June of 2037. Just ball parking the disparity, Im guessing the month value is hard coded at 30 days.

REALLY?
