Leap year is a year in the Gregorian calendar that contains an extra day, making the leap year 366 days long instead of 365 days long. The extra day added into a leap year is always February 29th. Leap years generally occur every four years, unless that year may be evenly divided by 100 but not evenly divided by 400. Leap years are necessary because a solar year is slightly longer than 365 days and over time, the calendar will become out of sync with the natural seasons if adjustments are not made. The term leap year comes from the fact that normally, fixed holidays advance one weekday every year, but in a leap year holidays leap ahead an extra weekday.
