Calendar Completion

Compute dates on an annual calendar

This worksheet shows a full year calendar with lots of missing pieces. The task of the student is to fill in some of the missing information. (If you want them to fill in the whole thing you can certainly do that too.) Students who are good at this should be quickly adding and subtracting 7s in their heads to find the missing dates. At the highest difficulty, they will also need to know the number of days in each month since there are few clues after February.
