Time Duration Calculator

Calculating Time Duration Made Easy

Knowing the exact duration between two times is essential for countless everyday tasks. Whether tracking work hours for a timesheet, calculating flight duration, or managing overnight shifts, this calculator gives precise results instantly.

The duration calculator handles overnight spans correctly. If start time is 10:00 PM and end time is 6:00 AM, it returns 8 hours. Results are shown in hours, minutes, seconds, and decimal hours commonly required for timesheets and billing.

The add/subtract feature is equally useful. Enter a base time and amount to add or subtract. The calculator wraps around midnight, indicating whether the result falls on the same day, next day, or previous day. Both tools update results live as you type.
