Date units converter
Convert between days, weeks, months, years, hours, and minutes. Free time unit converter for planning and date math.
Approximate calendar conversions
Days and weeks are exact, but months and years are averages because calendar months are different lengths and leap years add extra days. This converter uses 30.4375 days per month and 365.25 days per year.
When to use it
Use this date unit converter for planning rough timelines, translating 90 days into weeks, estimating months from days, or comparing hours and minutes for shorter durations.
For exact dates
If you need an exact calendar date, use the add or subtract date calculator instead. It walks the calendar rather than using month averages.
