Which sentence demonstrates proper time notation?

• A. 1:30 p.m.
• B. 1:30 p.m
• C. 1:30 PM
• D. 13:30

Answer: (A)

In proper time notation, you write the time in the 12-hour format and include a space before the meridiem indicator, with the letters in lowercase and followed by periods. 1:30 p.m. fits this standard because it shows 1:30, then a space, then p.m. with periods. The other forms break these conventions: 1:30.p.m uses a misplaced period and no space, 1:30 PM uses uppercase letters without the periods, and 13:30 uses 24-hour time without any a.m./p.m. indicator. So the first form is the correct illustration of proper time notation.
