No, it's not quite March 1.
Every four years, we add an extra day to the calendar to keep in sync with the Earth’s revolutions around the sun. It takes 365.242199 days for the Earth to complete a full rotation around the sun.
Our calendar, however, marks out a mere 365 days a year. If we did not add a day every four years, we would lose six hours from our calendar every year. That would add up to the loss of 24 days in the course of 100 years.
