Time Converter

How it works

Every time conversion here routes through the second, the SI base unit, so any pair can be linked: seconds, minutes, hours, days, weeks, months and years. The short units are exact by definition: 60 seconds in a minute, 3,600 in an hour, 86,400 in a day. Those numbers are worth knowing — 86,400 in particular turns any per-day rate into a per-second one instantly. The long units are where precision ends. A month has no fixed length, so conversions use an average of about 30.44 days, and a year averages 365.25 days to absorb leap years. For anything legal, financial or scheduled, count actual calendar dates rather than multiplying by an average — that is what a date-difference calculator is for.
