Add Time Calculator

Adding time together manually seems to be an easy task for most of us. For example, if you want to identify how much time you spent on two meetings this morning, which lasted 45 and 30 minutes, respectively, you just need to sum them up and have the calculation results of 75 minutes, or 1 hour and 15 minutes. 

However, it is not that easy when it comes to much more complicated calculations having several time units like day, hour, minute, and second at one. If that’s the case, using the Add Time Calculator is more than a perfect option.

Basic Rule to Remember: Different time Units & Conversion

Before diving into instructions on how to add time manually, you need to understand how different time units relate to each other and how to convert between them:

• 1 minute = 60 seconds
• 1 hour = 60 minutes
• 1 day = 24 hours
• 1 month = 30 days if it’s April, June, September, or November.
• 1 month = 31 days if it’s March, July, May, October, August, December, or January. (In February, there are 28 days in a regular year or 29 days in a leap year.).

7-Step Guide to Manually Adding Time Together

Now, we'll walk through how to manually add time, with the example of calculating your total work time for today, which includes 3 hours, 30 minutes, and 45 seconds (in the morning) and 3 hours, 2 minutes, and 30 seconds (in the afternoon).

Step 1. Add the seconds first. If the total seconds exceed 59, simply subtract 60 from the seconds and then carry 1 to the “minute” unit.

For example: Total seconds = 45 + 30 = 75 seconds.

Since the second number is greater than 59, you need to subtract 60 from 75 and add “1” to the minute unit in Step 2, resulting in 15 seconds and 1 minute.

Step 2. Next, add the minutes together, including all minutes carried over from adding seconds in the previous step.

For example: Total minutes = 30 + 2 + 1 (in Step 1) = 33 minutes.

Step 3. Check if total minutes exceed 59. If they do, subtract 60 from the minutes and carry 1 to the “hour” unit

Step 4. Calculate the total hours (don’t forget to add any hours carried over from calculating minutes in Step 3).

For example: Total hours = 3 + 3 = 6 hours.

Step 5. Check if total hours exceed 24. If they do, subtract 24 from the hours and carry 1 to the “day” unit.

Step 6. Add the total days, including all carried over from adding hours.

Step 7. Combine the total seconds, minutes, hours, and days.

For example: Total Time = 15 seconds + 33 minutes + 6 hours = 6 hours, 33 minutes, and 15 seconds.

So, your total hours worked for today is 6 hours, 33 minutes, and 15 seconds.

Add Time Using Excel

The SUM function in Excel allows you to calculate the total time with ease.

Step 1. Enter your time values in separate cells, ensuring they are formatted correctly as time (e.g., 1:30 for 1 hour and 30 minutes).

Let’s say you want to add 2 hours and 30 minutes (2:30), 2 hours and 15 minutes (2:15), and 2 hours and 21 minutes (2:21). So, enter 1:30, 3:15, and 2:21 in cells A1, A2, and A3, for example.

Step 2. To add these times, input the formula =SUM(A1:A3) in another cell and press Enter.

In this example, the total time is 7:06 (or 7 hours and 06 minutes).

Note: If the total exceeds 24 hours, you may need to format the result cell using [h]:mm to display the correct duration. This format ensures that hours beyond 24 are shown accurately.

To do that, simply right-click the result cell and select “Format Cell”. Next, in the Format Cells dialog box, head to the "Number" tab, then select "Custom" from the list on the left. In the "Type" field, select the [h]:mm:ss option. This format tells Excel to display hours beyond 24 correctly. Finally, click “OK” to apply the new format.
