There was an extra day because it was a leap year
A bissextile year, more commonly known as a leap year, is a year that contains an extra day, February 29th. Leap years occur every four years to help align the calendar year with the solar year, which is about 365.25 days long. This extra day is added to compensate for the slight discrepancy between the two.
To make the year start more or less in the same season every year, an extra day is added every four years.
