Cách sử dụng máy tính này
- Enter the start date and time.
- Enter the end date and time.
- The elapsed time appears in days, hours, minutes and seconds, and as totals.
Công thức
Both moments are converted to seconds on the same clock and subtracted. The calculation uses local wall-clock time, so a daylight-saving change in between does not add or remove an hour.
Duration = end − start
1 day = 86,400 s; 1 hour = 3,600 s
Example
- From Monday 08:00 to Wednesday 17:45.
- = 2 days, 9 hours, 45 minutes.
- = 57.75 hours = 3,465 minutes.
Câu hỏi thường gặp
What about time zones?
Both times are treated as being in the same time zone. To compare times in different zones, first convert them with the time zone calculator.
What about daylight saving time?
Wall-clock time is used. If you need elapsed physical time across a DST change, add or subtract the one-hour shift.
How do I find hours worked?
For daily shifts with breaks, the hours calculator is simpler.
