1st grade commas in dates worksheets
Dates carry two comma rules: one between the day and the year (July 4, 2019), one after a weekday (Monday, June 8). First graders learn where the comma lives, and where it never goes: between the month and its number.

How to teach this
Anchor the rule to your child's own birthday; nobody forgets the punctuation of a date they own. Write it three ways, one correct and two wrong, and play find-the-real-one. The wrong option with a comma after the month (July, 4) is the error to name out loud.
Watch for: No comma goes between the month and its number: June 8, never June, 8. Month and year alone need no comma: June 2026.
Common questions about commas in dates
- Where exactly does the comma go in a date?
- Between the day and the year: March 14, 2026. If a weekday leads, it takes a comma too: Saturday, March 14. The one place a comma never goes is between the month and the day; March, 14 is always wrong, and it's the trap these worksheets teach kids to spot.
- Why does my child write "June, 8"?
- It's a sensible overgeneralization: they've learned dates involve commas and are spreading them around. The fix is the plain rule, month and day stay glued together, plus a few practice rounds of choosing the correct version. It fades quickly.
