Why do we have a leap year?
Leap years are needed to keep our calendar in alignment with the earth’s rotation around the sun.
It takes the earth approximately 365 days, 5 hours, 48 minutes, and 46 seconds to circle once around the sun.
If we didn’t add a day in February (29) every 4 years we would lose almost six hours every year.
After about 100 years our calendar would be off by approximately 24 days. To counteract we have every 4 years a leap year.
