What it is
Time Converter turns milliseconds, seconds, minutes, hours, days, weeks, months and years into each other as you type. 90 days equal about 2.96 average months, and 1000 hours equal about 41.67 days: useful for estimating deadlines, subscriptions or project durations. Months and years don't have a fixed length on a real calendar, so this tool states the average value it uses explicitly — 30.4375 days for the month, 365.25 days for the year (accounting for leap years) — instead of leaving it implicit like the few competitors that include these two units.
- From milliseconds to years: 8 units, including those with variable calendar length
- 90 days ≈ 2.96 average months, 1000 hours ≈ 41.67 days: quick estimates for deadlines and subscriptions
- Average month (30.4375 days) and year (365.25 days) stated clearly, not left implicit like elsewhere
How it works
Pick the starting unit
Choose from ms, seconds, minutes, hours, days, weeks, months or years.
Type the value
Enter the number to convert: the result in the other unit appears instantly.
Check the common table
Below the result you'll find standard multiples already converted, useful for estimating typical durations.
Features
Average month and year, value stated
The month uses 30.4375 days and the year 365.25 days (the calendar average, including leap years): the exact value is stated clearly, not left implicit like in the few competitors that include these two units.
From milliseconds to years
ms and seconds for technical use, days and weeks for everyday life, months and years for long-term planning: 8 units in one tool.
Common conversions table
Reference durations (7, 30, 90, 365...) already calculated below the result, for quick estimates without a calculator.
Linked to the speed converter
Speed is distance divided by time: also use the speed converter and the length converter for the values that make it up.
FAQ
30.4375 days: the calendar average (365.25 days a year divided by 12 months), stated explicitly because real months range from 28 to 31 days.
365.25 days: the average that accounts for one leap year every 4 years, not the 365 days of a common calendar year.
Because on a real calendar, months last 28 to 31 days and leap years add a day every 4 years: any converter has to pick an average value, and this tool states it instead of leaving it implicit.
72 hours (3 × 24).
Speed is distance divided by time: convert the distance with the length converter, the time with this tool, then divide the two values and convert the result with the speed converter.
