Minutes to Common Years (min to yr (365))
1 minute equals 0.000001902587519 common years (rounded).
How to convert minutes to common years
To convert minutes to common years, multiply the number of minutes by 0.000001902587519. The factor is rounded to 10 significant digits. To go the other way, multiply common years by 525,600.
common years = minutes × 0.000001902587519
Example: 10 minutes = 0.00001902587519 common years.
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
Minute (min)
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).

Common Year (yr (365))
A calendar year of exactly 365 days, without a leap day.
Calendar makers needed whole numbers of days, so the common year is simply 365 of them, or 31,536,000 seconds at 86,400 seconds per day. It makes up 303 of every 400 years in the Gregorian calendar. Because 365 is 52 weeks plus one day, a common year begins and ends on the same weekday, and each date falls one weekday later than the year before.
The trouble is that the Earth takes about 365.24 days to complete a cycle of seasons, so a common year runs roughly 5 hours, 48 minutes and 46 seconds short of the tropical year. The shortfall adds up to a full day in about four years, which is why leap years exist. NIST lists the 365-day year as an exact conversion, while its tropical and sidereal years are measured quantities that differ in the fifth significant figure.
1 common year = 31,536,000 seconds (exactly).
