Why leap year and why there is an extra day

The length of a solar year is about 365,25 days. To compensate for this every fourth year has one extra day.

  • Ordinary year has 365 days.
  • Every fourth year it’s a leap year which has 366 days. Next leap year?

The extra day is always added to February. This is why February has 28 or 29 days.
