Final answer:
Most states celebrate Presidents' Day on b) February 22nd to honor the birthday of George Washington.
Step-by-step explanation:
Most states celebrate Presidents' Day on February 22nd. This date is observed to honor the birthday of George Washington, the first President of the United States. Due to the implementation of the Gregorian calendar, Washington's birthday, which was originally on February 11th, became February 22nd in the new calendar system.
Thus, it was originally established to honor the birthday of George Washington, the first president of the United States. However, over time, it has come to also recognize and honor all past and present presidents of the country. The third Monday in February was chosen as the date for Presidents' Day to create a long weekend for Americans, as it falls between the birthdays of George Washington (February 22) and Abraham Lincoln (February 12).
