Time Calculator · Add and Subtract Time
Calculate the time between two times, the time after or before a duration, the time between two dates, and convert between days, hours, minutes and seconds.
⏱️ Time between two times
Calculates how much time passes from the start time to the end time. If the end time is earlier, it is treated as the next day.
🕒 Time after / before a duration
Finds the clock time a given duration after (or before) the start time.
📅 Date & time plus / minus a duration
Finds the date and time a given number of days, hours, minutes and seconds after (or before) the start.
⏳ Time between two dates & times
Shows the time between two dates & times and converts it to days, hours, minutes and seconds.
🔁 Time conversion
Normalizes a duration into days, hours, minutes and seconds and converts it to each unit. e.g. 1h 5m 10s → 3,910 s, 5000 s → 1h 23m 20s
Find how long it is between two clock times — working hours, sleep or travel time. If the end time is earlier than the start, it is treated as the next day.
Add or subtract days, hours, minutes and seconds from a start date and time, or convert a duration into each unit. For example, 1 h 5 min 10 s = 3,910 seconds and 5,000 seconds = 1 h 23 min 20 s.
