February 29 is a leap day - an extra 24 hours added to the shortest month in a leap year.
If we stuck with the notion a tropical year was only 365 days long, after 100 years our calendars would have shifted forward by 25 days.

It's basically a corrective measure because the earth doesn't orbit the sun in exactly 365 days - it's a little more than that - so February 29 can help the planet and our calendars keep in sync.
Leap years are named as such because the extra day causes each date on the calendar to jump ahead by two days compared to the last year, rather than one.

It took centuries, but the Gregorian calendar was eventually adopted worldwide, and is the one we still use today. Iran, for example, doesn't.
