Washington, Feb 19: The entire United States establishment, along with private enterprises, schools and other institutions remained close today to observe the Presidents' Day. Both federal and provincial governments have declared the day as an official holiday. President Donald Trump on Monday wished the nation on Twitter saying, "Have a great, but very reflective, President’s Day! (sic)."

What is the Presidents' Day and Why US Observes a Holiday Today?

The US celebrates an annual holiday every third Monday of February to pay tribute to the country's most revered presidents - George Washington and Abraham Lincoln - both of their birth anniversaries being observed in this month.

While Washington was born on February 22, 1772, Lincoln's date of birth was recorded as February 12, 1809.

However, not all provincial governments - especially in southern US - pay homage to Lincoln as well. Others, meanwhile, also pay homage to Republican icon and late president Ronald Reagan - who was born on February 6, 1911.
