Time Converter

Time Converter converts a duration between nanoseconds, microseconds, milliseconds, seconds, minutes, hours, days, weeks, fortnights, months, years, decades and centuries.

Seconds are the base, and while the short units are exact the long ones cannot be. A month is stored as the average Gregorian month of 2,629,746 seconds and a year as 31,556,952 seconds, which is 365.2425 days including the leap rule; both attach a note to the answer, because a real calendar month runs 28 to 31 days and a common year is 31,536,000 seconds. The Julian year of 365.25 days is a separate entry for when that is the definition your source used. This is duration arithmetic only — it will not tell you which date falls ninety days from today.

The duration is converted locally, with no request and no history kept. The value is not written into the URL either, so it is not left behind in a browser history entry or a shared link.
