Enter your start time, end time, and break duration into the calculator to determine your total ET (Elapsed Time).
ET Calculation Formula
The following formula is used to calculate the total elapsed time (ET) from your start and end times:
Total ET = (End Time - Start Time) - Break Duration
Variables:
- Total ET is the total elapsed time in minutes.
- Start Time is the time you begin your activity (HH:MM format).
- End Time is the time you finish your activity (HH:MM format).
- Break Duration is the total break time in minutes.
To calculate the total ET, subtract the start time from the end time and then subtract the break duration.
