Which abbreviation is used for the morning period?

Which abbreviation is used for the morning period?

• A. noon
• B. a.m.
• C. midnight
• D. p.m.

Answer: (B)

Morning hours on a 12-hour clock are labeled with a.m., which stands for ante meridiem, meaning before noon. This label is used for times from midnight up to just before noon, like 6:15 a.m. Noon is the middle of the day, and is not an a.m. label. Midnight is the start of a new day, written as 12:00 a.m., while p.m. is used for times after noon in the afternoon and evening. So the abbreviation used for the morning period is a.m.
