A trio of tips about time to get you over the hump:
- You don’t need :00 for a top-of-the-hour time (4 p.m. instead of 4:00 p.m.).
- When noting a time range that occurs wholly within a.m. or p.m., you need that designation only once (1 to 4 p.m. instead of 1 p.m. to 4 p.m.).
- Noon is clearer than 12 p.m. (or is it a.m.?) and midnight is clearer than 12 a.m. (or is it p.m.?).
