How to Use This Time Converter
Enter the time value you need converted into the input field. Select the unit you are converting from, choosing from the full list of supported time units. Then select your target unit.

Why Months and Years Use Average Values
Months vary in length from 28 to 31 days, which makes exact month-to-day conversion impossible without knowing the specific calendar month in question. This converter uses the standard average calendar month length of 30.44 days, which provides a reliable figure for general time conversion purposes. Similarly, years use 365.25 days to account for leap years, offering a consistent average rather than a single-year figure that would vary.
Pro Tip: For exact calendar month conversions, always specify the actual month and year. This tool uses average values (30.44 days/month, 365.25 days/year) for general planning purposes.
