How to Determine the Date Yourself
Because Memorial Day is defined as the last Monday in May, you can determine the date for any year by identifying the last Monday in that year’s May. For 2010:
- May 1, 2010 was a Saturday.
- Counting forward, the Mondays in May 2010 were May 3, 10, 17, 24, and 31.
- The last Monday was May 31, which is therefore the observed date.
This method applies consistently because the rule is anchored to the calendar position (last Monday), not a fixed day number.
