Lesson 339 - Mechanics - Punctuation - Periods

View lesson on Daily Grammar

Use a period with abbreviations used with figures showing time. Examples: A.M., P.M., B.C., and A.D.

Instructions: Put periods where needed in the following sentences.

1. I was born in A D 1940.

2. Be here at 4:30 A M , or you will not see me until 9:45 P M

3. What happened in A D 1776 that was of great importance?

4. People living in 2000 B C did not enjoy all that we have today.

5. Class starts promptly at 8:00 A M

--For answers scroll down.


1. A.D.

2. A.M. / P.M.

3. A.D.

4. B.C.

5. A.M.

(Notice that when a period is used for an abbreviation or some other reason at the end of the sentence, you do not need a second one to end the sentence. The one period does double duty.)
