When is the first day of summer 2021 in the US?
SUMMER has officially arrived in the Northern Hemisphere, signalling the start of longer days and warmer temperatures. It also marks the start of a annual celebration known as summer solstice, where events are held across the United States. The first day of summer 2021 was on Sunday, June 20. It officially started at 11:32pm Sunday in New York City, New Jersey and Philadelphia. On Sunday out on the west coast, it arrived at 8.32pm in Los Angeles and San Francisco, while summer started in Denver at 9.32pm and in Chicago at 10.32pm. The first day of the summer is known as the summer solstice and is celebrated yearly on June 20, 21 or 22. The day is also recognized as the longest day of the year in terms of daylight minutes. Some years summer arrives on June 20, and other years it starts on June 21 or June 22. Across the United States, summer solstice is widely celebrated similarly to Memorial Day weekend in late May. Some folks start their summer vacations on or around June 20, but many celebrate by holding big gatherings with food, alcohol and music. Some people even shed their clothes as part of their ritual to welcome the first day of summer. Summer runs from June 20 and through to September 22. However, many Americans consider the end of the summer to coincide with Labor Day, which is celebrated on the first Monday in September to honor and recognize the American labor movement. The event was first recognized as a public holiday in 1887. 4 A Labor Day parade in the 1990s Credit: Getty - Contributor  Most read in News Breaking DEADLY SHOOTING House party shooting leaves 3 people dead and 8 injured, cops say SHIP SHAKE US Navy detonates huge bomb by own aircraft carrier triggering earthquake CREEPY INTRUDER Naked man 'breaks into mansion & swims in pool before killing parakeets' 'IN CAR WITH STRANGER' US student found dead in Russia after cryptic 'abduction' text DIRTY POLITICS City Council candidate filmed wearing nipple clamps in S&M bondage session PARTY BLOODBATH 'Kids among four shot' at birthday party in horrific rampage  In the present day, it is celebrated via carnivals and music festivals as the Monday of the long weekend known as Labor Day Weekend.
