Time conversions are exact down to the day and approximate above it. Seconds, minutes, hours and days have fixed ratios, but a month has no fixed length and a year has two — 365 days in the calendar and 365.25 in the astronomical convention used here. For anything with legal or contractual weight, count the actual calendar dates rather than converting a duration, because the difference accumulates precisely where it is least welcome.
days to minutes formula
To go the other way, use day = minute ÷ 1,440.
About these units
A day is exactly 86,400 seconds by convention, though the Earth’s actual rotation drifts slightly against it — the discrepancy leap seconds were introduced to absorb.
The minute holds sixty seconds because Babylonian astronomy counted in base sixty — a convention that has outlasted every other part of the system.
Day is also written days. Minute is also written minutes and mins.
