The sum
| In | Sum | Minutes |
|---|---|---|
| A year of 365 days | 365 × 1,440 | 525,600 |
| A leap year of 366 days | 366 × 1,440 | 527,040 |
| The average year, 365.2425 days | 365.2425 × 1,440 | 525,949.2 |
Years and months are not all the same length. A year has 365 days, or 366 in a leap year. Over the calendar's 400-year cycle there are 97 leap years, so the average year is 365.2425 days and the average month is a twelfth of that. How leap years work.
