Time duration calculator
The exact time between two dates and times.
What this calculates
The exact length of time between two moments, shown as days, hours and minutes, and as totals in hours, minutes, seconds and days. It uses your device's time zone, so a span that crosses a daylight saving change is counted correctly (the spring-forward night has 23 hours).
Need just the clock times on one day? Use the hours calculator. Need whole days between dates? Use the date calculator.
