Date When Celebrated : Always March 15th
Dumbstruck Day is a day to be totally dumbstruck over the things you see, hear and read. You may easily be dumbstruck to read that someone created this special day. Some people are dumbstruck on a regular basis, day in and day out. The events in their lives and the world around them are overwhelming. Fortunately, that's not you (we hope).
However, everyone has their chance to be dumbstruck once in a while. If you are normally embarrassed to be dumbstruck, then today is truely a special day. Today, you can be dumbstruck like the rest of us without guilt or embarrassment.
