Why the President's Inauguration Ceremony is Held on 20th January in the USA?
It's cold, maybe even freezing. Sometimes it snows. So why do they have to have a huge outdoor event to inaugurate a new president on January 20? While their first president, George Washington, was smart enough to get himself inaugurated on a more balmy April 30, 1789. What went wrong?

But the Twentieth Amendment to the Constitution changed the date to January 20, and Franklin D. Roosevelt's second swearing-in ceremony in 1937 was the first held on the new date.

Even if you're cold and not-so-comfortable, it's always a special moment watching a new leader say these famous words: "I do solemnly swear that I will faithfully execute the office of the President of the United States, and will to the best of my ability, preserve, protect, and defend the Constitution of the United States."
