What is Patriots Day 
Never heard of it.
Patriots' Day (sometimes spelled Patriot's Day or Patriots Day) is a civic holiday in the U.S. states of Massachusetts[1] and Maine[2] (once part of Massachusetts), and a public school observance day in Wisconsin[3]. Traditionally it was observed on April 19, in honor of Lexington and Concord, the first battles of the American Revolutionary War, fought on that date in 1775. Since 1969, however, the holiday has been observed on the third Monday in April, providing a three-day long weekend. Observances and re-enactments of these first battles of the American Revolution occur annually at Lexington Green (~6am) and Minute Man National Historic Park (~9am).
Worth learning in any state.
