About National Oyster Day
History & origins
August 5 is the date U.S. food calendars most often use for National Oyster Day. No verified single founder is documented. Oyster harvests and festivals on the Atlantic, Gulf, and Pacific coasts are much older than the named day.
Why it matters
The day is a chance to eat a regional shellfish carefully and to notice the reefs and water quality that oysters depend on.
How to celebrate
Order oysters on the half shell, try a roast or stew, or support a reef-restoration project if you live near the coast.
