Early May: May 1 - May 9
Mid May: May 10-May 20
Late May: May 21-May 31
For bugging me a day too early, I shall have to assess a 5-day penalty.

On a more serious note, late May for me doesn't officially begin until Friday, an hour after my semester ends and all my papers are graded! I love the idea. It's much better than re-inventing the wheel and trying to put a spreadsheet inside Gravity Simulator. So stay-tuned. I'll do it soon.
