Q.O.D. = every other day. Q.A.D. = every alternate day. Technically speaking, I would be hard pressed to find a difference.

The abbreviations am and pm derive from Latin: Using numbers from 1 to 12, followed by am or pm, the 12-hour clock system identifies all 24 hours of the day. For example, 5 am is early in the morning, and 5 pm is late in the afternoon; 1 am is one hour after midnight, while 11 pm is one hour before midnight.
