Enter the ending time and starting time into the calculator to determine the time difference.

## Subtract Time Formula

The following formula is used to calculate the difference between two given times.

TD = T2 - T1

Variables:

• TD is the time difference (in the unit of time being used)
• T2 is the ending time (in the unit of time being used)
• T1 is the starting time (in the unit of time being used)

To calculate the time difference, subtract the starting time from the ending time. This will give you the duration of the event, the time taken to complete a task, or the time difference between two locations. The unit of time used for the calculation will depend on the level of precision required. For example, if you are calculating the time difference in hours, then T2 and T1 should also be in hours. If you are calculating the time difference in minutes, then T2 and T1 should be in minutes, and so on.

## What is a Subtract Time?

Subtract Time refers to the process of calculating the difference between two given times. This is often used in various fields such as project management, logistics, and transportation to determine the duration of an event, the time taken to complete a task, or the time difference between two locations. The subtraction can be done in various units such as hours, minutes, seconds, or even milliseconds, depending on the level of precision required.

## How to Calculate Subtract Time?

The following steps outline how to calculate the time difference using the formula TD = T2 – T1.

1. First, determine the starting time (T1) and the ending time (T2) in the unit of time being used.
2. Next, subtract the starting time (T1) from the ending time (T2) using the formula TD = T2 – T1.
3. Finally, calculate the time difference (TD).
4. After inserting the values of T1 and T2 into the formula and performing the subtraction, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Starting time (T1) = 10:30 AM

Ending time (T2) = 2:45 PM
