About Time Converter
Time conversion is ratio-based against the second: a minute is 60 seconds, an hour 3600, a day 86,400, and a week 604,800. Those factors are exact and never change.
Months and years are not exact. Calendar months run from 28 to 31 days and years are 365 or 366, so this converter uses the common approximations of 30 days for a month and 365 days for a year. For anything date-specific, use the date calculator instead, which counts real calendar days.
Need a different kind of unit? The Unit Converter covers length, weight, temperature, data storage, area, speed, time, and volume on one page.
