Years to Moments (yr to moment)
1 year equals 350,632.8 moments exactly.
How to convert years to moments
To convert years to moments, multiply the number of years by 350,632.8. This factor is exact. To go the other way, multiply moments by 0.000002851986466 (rounded).
moments = years × 350,632.8
Example: 10 years = 3,506,328 moments.
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.
Approximate value. Standards for the moment varied by place and period, so this converter uses the most commonly cited value. Treat results as estimates, not exact figures.
About these units
Year (yr)
The average Gregorian calendar year of 365.2425 days (31,556,952 seconds). A common year has 365 days and a leap year 366.
A year is the Earth's trip around the Sun, but there are several versions. The tropical year, which tracks the seasons, is about 365.2422 days. The sidereal year, measured against the stars, is about 365.2564 days, roughly 20 minutes longer, because the Earth's axis precesses. Calendars must squeeze these into whole days, which is the origin of leap years. English year descends from Old English gear, while Latin annus, the source of annual, comes from a different root.
The Gregorian calendar, introduced by Pope Gregory XIII's bull of 24 February 1582, fixed the problem of Julian drift that had moved the March equinox away from 21 March and upset the date of Easter. Ten days were skipped, so Thursday 4 October was followed by Friday 15 October. Its rule of skipping leap days in century years not divisible by 400 gives a mean year of 365.2425 days, the value this site uses for the year. Britain and its empire switched in 1752 and Russia in 1918. Scientists write the year as a, with the Julian year fixed at 31,557,600 seconds.
1 year = 31,556,952 seconds (exactly).

Moment (moment)
About ninety seconds, one fortieth of a solar hour. A medieval unit of time described by the English monk Bede.
Medieval computists, the scholars who worked out the calendar and the date of Easter, used the moment as a small slice of the hour. The Venerable Bede described it in the 8th century. It was one fortieth of a solar hour, measured by the motion of a sundial shadow, and since the solar hour varied with the season, the moment was not fixed.
On average a moment equalled about 90 seconds, which is the figure used here. Bede's scheme also had the punctum at four per hour, the minutum at ten and the pars at fifteen, so a day held 960 moments. Bartholomeus Anglicus and Roger Bacon later wrote about the system, and Bacon subdivided the moment into 12 ounces of 47 atoms each. The modern phrase a moment is much looser, and the ostent that Bacon mentioned is seen as a forerunner of the modern minute.
1 moment = 90 seconds (approximately).
