February 29th is a leap day, which occurs every 4 years. However, what is a leap year and why do we have them? We use leap years to keep our calendar in sync with the seasons. They are years where an extra day is added to the end of the shortest month, ie. February, making it 366 days in the year instead of the usual 365 days. 

Leap days help keep our modern day Gregorian calendar in alignment with the Earth's revolution around the Sun. If a leap day wasn't added on February 29th almost every four years, each calendar year would begin approximately 6 hours before the Earth completes its cycle around the Sun. The leap day fixes that error by giving the Earth the additional time it needs to complete the full cycle.
