Question

which date is correctly punctuated?
january, 7, 2001
january 7 2001
january, 7. 2001
january 7, 2001

Explanation:

In American English date formatting, when writing the month followed by the day and year, no comma is placed after the month (only after the day). The first option incorrectly adds a comma after "January", the second omits the required comma after the day, and the third has both an incorrect comma after "January" and uses a period instead of a comma after the day. The fourth option follows the correct rule: month, day followed by a comma, then year.

Answer:

January 7, 2001
