Here are the events.

day abbreviations (SMTWRFA))

S = sunday

M = monday

T = tuesday

W = wednesday

R = thursday

F = friday

A = saturday

I woud also like a TimeInterval class that can that represent an interval of time, suitable for events (such as a meeting on a given date from 10:00 - 11:00). Provide a method to check whether two intervals overlap.
