# How To Calculate Time Duration Using Different Methods?

# Effortlessly Calculate Time Duration with Allcalculator.net's Time Duration Calculator

Welcome to **Allcalculator.net**, your ultimate destination for accurate time duration calculations. With our **Time duration calculator**, you can effortlessly determine the duration between two points, such as 8:00 am and 6:45 pm, and obtain precise results like 10.75 hours or 10 hours and 45 minutes.

However, you can conveniently use a Time duration calculator or manually perform the calculations. Calculating time differences can serve various purposes, such as computing work hours for payroll, time cards, or salaries.

With our calculator, adding or subtracting time is a simple task. You can utilize the + operator to add times and find out the duration of future events. Alternatively, you can calculate the time difference between two points by subtracting them.

**Calculating time duration by hand**

To manually calculate the time difference, follow these steps:

- Use the 24-hour format for ease of computation. Add 12 to all pm hours if required.
- Convert the start and end times to minutes. The end time minutes must be subtracted from the start time minutes.
- You need to subtract an hour from the end time hours and add 60 minutes to the end time hours if the start minutes exceed the end minutes.
- Subtract the end time hours from the start time hours. The time duration calculator helps you get the outputs instantly and acquire error-free results.
- Combine the results of hours and minutes to determine the total duration.

**Calculate time duration using a Date Calculator or a calendar:**

If you need to calculate the duration between two dates, you can use a calendar or date calculator. This method is commonly used to calculate the number of days between two dates, such as the duration of a vacation or a project deadline.

**How to calculate time duration using a Simple Formula? **

If you want to estimate time differences using a **Time duration **calculator, you can calculate easily in Excel using a simple subtraction formula. All you’ll need to enter the details like:

- Input a formula in a specific cell.
- Make a cell of the ‘ending time’ and the ‘starting time.’ Enter the values and subtract the values from the ending time from the starting time. Resultant, you’ll get the duration in the new cell.
- Click ‘enter’ to see the output in time format.

**How to calculate time duration using a ‘TEXT’ function? **

Using a ‘TEXT’ function, you can easily estimate the time duration in the given format. At first, you’ll need to input the formula in a new cell; let us suppose D3. The required formula will estimate the time duration once you subtract the values of cell B3 with the C5 in the format of the hour: minute: second.

Click enter, and you can get the time difference in cell D3. Draw out cell D3 with the end of your full data set.

**Calculate time duration using Math Formulas: **

If you need to calculate the duration between two events in terms of seconds, minutes, or hours, you can use mathematical formulas. For example, to calculate the duration in seconds with the Time duration calculator**,** you can multiply the number of hours by 60 and add the number of minutes, then multiply by 60 again to get the total number of seconds.

**Calculating time difference in Hours:**

Excel spreadsheet allows you to number 1 with the 24 hours in a day. Hence, from 00:00 am up to 12:00 pm, it has a zero value and assigns 0.999 to 11:59 pm. The time between such duration obtains a fraction as ‘one.’ Hence, once you multiply the time by the difference of 24, you can get the time interval in hours.

Enter the formula in the required cell of D4. The formula in the cell will deduct the cell B4 with the C4 and then multiply it with the value of 24. Resultant, you can get the time interval in the cell of D4.
