Minutes to Years

About Minutes and Years

Minutes (min): Sixty seconds; comes from the Latin pars minuta prima, 'first small part' (of an hour), with the second coming from pars minuta secunda, the second small part. Common uses: Cooking times, exercise intervals, scheduling, transit timetables, and most everyday time intervals between seconds and hours.

Years (yr): 365.25 days in the Julian convention (used here); 365.2425 days in the Gregorian calendar; or 365.24219 days in the actual tropical year (the time between vernal equinoxes). Common uses: Birthdays, contract lengths, project lifecycles, financial planning, and any time period longer than a few months.

How the conversion works

Time uses fixed SI seconds. A day is exactly 86,400 seconds; a year (Julian) is 365.25 days = 31,557,600 seconds.

The exact relationship is years = minutes × 1.90128527e-6, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.

When this conversion matters

Converting between minutes and years comes up wherever time measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
