Using this time converter
Convert elapsed durations for schedules, operating-hour records and estimates using fixed-length time units.
Month is fixed at 30 days and Year at 365 days in this tool. These are duration conventions, not calendar arithmetic.
Check before using the result
- Use a date calculator for calendar months, leap years, working days or the time between two dates.
- Local clock times can cross daylight-saving changes. This tool converts a supplied duration and does not interpret time zones.
Definitions and method: NIST: unit conversion factors and rounding. Calculations use double-precision arithmetic; the display precision can be adjusted above.
