WHY FEBRUARY HAS 29 DAYS IN LEAP YEARS? |
| Although most modern calendar year have 365 days, a complete revolution around the sun (one solar year) takes approximately 365 days and 6 hours. An extra 24 hours thus accumulates every four years, requiring that an extra calendar day be added to align the calendar with the sun's apparent position. |
