Buckman Tavern is a historic American Revolutionary War site associated with the revolution's very first battle, the 1775 Battle of Lexington and Concord. It is located on the Battle Green in Lexington, Massachusetts and operated as a museum by the Lexington Historical Society.
The revolution's first battle happened more than 2 billion seconds ago.
2 billion seconds is 63.42 years and it happened in 1775. It's difficult because such large numbers always make the system think the statement is incorrect.
