Memorial Day 1. Memorial Day is a day in which people who died in the military are remembered. 2. Memorial Day is on the last Monday of May, being on the 30th. 3. A few ways to show honor on Memorial Day are to fly to flag, you can also say thank you or right a thank you letter to anyone that is serving in the army, military, etc. You can as well stop by to a families house that you know has a member serving to show appreciation. You can attend a memorial service. 4. I will have a moment of silence to honor those who died in the military, etc. I will as well attend any Memorial Day parade their might be.
