How to convert leap years to minutes

To convert leap years to minutes, multiply the number of leap years by 527,040. This factor is exact. To go the other way, multiply minutes by 0.000001897389192 (rounded).

minutes = leap years × 527,040

Example: 10 leap years = 5,270,400 minutes.

Months and years are not constant. This site uses the average Gregorian year of 365.2425 days, so one 'year' converts to 365.2425 days, not 365; use 'common year' for exactly 365 days.

About these units

Leap Year (yr (366))

CalendarCurrent unit

A calendar year of exactly 366 days, with the leap day on February 29.

Julius Caesar's edict, effective 1 January 45 BC, turned the Roman calendar into a solar one with an extra day every fourth year. The English phrase is thought to come from weekdays: a fixed date normally moves ahead one weekday each year, but after a leap day it moves two, appearing to leap over one. The extra day is 29 February, used since about the fifteenth century, and British law recognized it formally in 1750.

A leap year has 366 days, or 31,622,400 seconds. The Gregorian rule, which now governs most of the world, makes a year a leap year when divisible by four, except century years that are not divisible by 400. So 2000 was a leap year and 1900 was not. That leaves 97 leap years in each 400-year cycle and a mean year of 365.2425 days, close to the tropical year.

1 leap year = 31,622,400 seconds (exactly).

Minute (min)

Metric (SI)Current unit

60 seconds. Defined as one sixtieth of an hour.

Minute means small, not short. It comes from the Latin pars minuta prima, the first small part, produced when sixty-based division was applied to the hour. Al-Biruni is credited with dividing the hour into minutes, seconds, thirds and fourths around the year 1000, and Roger Bacon used the same scheme in 1267. For everyday life the minute needed hardware: Jost Bürgi is said to have made the first clock with a minute hand, for Tycho Brahe in 1577, and watches got minute hands only after Thomas Tompion's hairspring of 1675 made them accurate enough.

A minute is 60 seconds, exactly 1/60 of an hour, and the BIPM's SI Brochure is the reference for its symbol, min. Civil timekeeping can bend the rule: because of leap seconds, a UTC minute occasionally holds 61 seconds. A negative leap second would produce a 59-second minute, but that has never happened in more than 40 years. People use the minute for cooking, lectures and phone calls, and the same name serves for the arcminute, which is a sixtieth of a degree.

1 minute = 60 seconds (exactly).
