Leap year 2024: How the extra day affects birthdays, deadlines and contracts. February will have an additional day on February 29th in 2024, meaning that the calendar year will now have 366 days instead of 365.

Even though you work one more day in a leap year, you don't get paid more. In the last leap year of 2020, when the additional working day fell on a Saturday, fewer people were affected. This year's leap year falls on a Thursday, but February remains the shortest month.
