Which date commemorates the founding of the U.S. Marine Corps?

The date that commemorates the founding of the U.S. Marine Corps is November 10, 1775. This date is significant because on that day, the Continental Congress passed a resolution to raise two battalions of Marines. This decision marked the official establishment of the Marine Corps as a separate fighting force from the Continental Navy. Over the years, November 10 has become a day of celebration and remembrance for Marines, honoring their heritage and the sacrifices made by those who have served in the Corps.

It's important to recognize that the other dates listed correspond to different events or milestones in American military history, but none mark the formal founding of the Marine Corps.
