Time calculator allows you to add or subtract two time values. In addition, you can find the time duration between two times.

Time Calculator is used to add or subtract two provided times. Also, it makes finding the duration between two times super simple. Just fill in the time values in the input boxes. As a result, you will get the final output on your screen within a second.

Also, you should try some more time-calculating tools such as time clock calculator, date of birth calculator, and days calculator.

Our time calculator works on pre-defined algorithms and there is a strong javascript code written to make your time calculations easier, faster, and more accurate. You just need to follow the instructions below:

Firstly, you need to input two times. The first input value should be the start time and the second one should be the end time. Make sure the input format should be this: **YYYY/MM/DD - hh/mm/ss**. Because if you don't enter the values in the right format, you won't get the true results.

Also, it's not necessary to enter all the time values. For example, if you want to add or subtract only hours and minutes then you can only enter those values. No need to enter years, months, days, and seconds. Just keep those input fields empty. But make sure to enter at least one value for start and end time.

The second step is to select the operation between Addition or Subtraction. If you want to add two times, you can choose **"Addition"**. Similarly, if you want to subtract two times, you can select **"Subtraction"**.

Lastly, press the **"Calculate"** button to get the final duration result. Also, you will get the output in years, months, days, hours, minutes, and seconds.

For new time calculations, you can use the **"Reset"** button.

It's very simple. Let's understand it using an example.

Add 2 hours, 45 minutes, and 30 seconds with 3 hours, 50 minutes, and 20 seconds.

Here, after performing the addition, the minutes we get are 95. So, we have removed 60 minutes and added 1 hour to the total hours.

Therefore, the final output after the addition is **6 hours, 35 minutes, and 50 seconds**.

Subtract 2 hours, 30 minutes, and 20 seconds from 3 hours, 50 minutes, and 30 seconds.

After subtraction, we get **1 hour, 20 minutes, and 10 seconds**.

The manual calculation is not so easy at all times. Therefore, it's better to use our time calculator for complex calculations. It's time-saving and more accurate.
