#SUBTRACT DATE TIME CALCULATOR HOW TO#

For example, if you have to subtract 1 h 20 min 30 s from 2 h 14 min 16 s, you may first convert them to seconds, and we have a time unit converter to assist you for that:Ĭonvert the result to the target unit by dividing it by 60 (the remainder becomes the seconds):

Now, let's go through some examples of how to add and subtract time when you don't have access to time math calculators.Ĭonvert Time 1 and Time 2 to simpler units if you need to. It allows you to calculate between two dates. While seconds and hours obey the sexagesimal system:īefore we get into it, may we interest you to check out our date calculator. It's probably because we're used to using the decimal system: The formatting in cell D2 is copied along with the formula.Adding and subtracting time on your own can be confusing. To get the results for Joy and Leslie, copy the formula by clicking in cell D2 and dragging to cell D4. In cell D2, subtract the end time from the start time by typing the formula: =C2-B2, and then pressing Enter. Now we see that Richard worked 3 hours and 45 minutes. Type the other start and end times for your friends Joy and Leslie. In cell C2, type the end time, including “ a” or “ p” as appropriate, and press Enter. In cell B2 type the start time, enter a space, and then type “ a” for AM or “ p” for PM, and press Enter.

In other words, you want the elapsed time or the difference between two times. Say you and your friends know your start and end times at a volunteer project, and want to know how much time you spent. Press Enter to get the result, 16 hours and 15 minutes. The formula will look like this: =SUM(B2:B3). Tip: You can also add up times using AutoSum. In cell B3, type the formula =(B2-B1)*24. In cell B2, do the same for the end date. In cell B1, type the start date, including month/day/year and time using either “ a” or “ p” for AM and PM. The new format will be available when you need it in the Type list. Notice the empty space at the end of yyyy and at the end of mm. In the Type box, at the top of the list of formats, type m/d/yyyy h:mm AM/PM. Referring to the above example, select cell B1 and drag to cell B2 so that you can apply the format to both cells at the same time.

It is necessary to create a formula to subtract the difference between two times that total more than 24 hours. To subtract time that’s more than 24 hours: The formatting in cell D2 is copied along with the formula. To get the results for Joy and Leslie, copy the formula by selecting cell D2 and dragging to cell D4. Now we see that Richard worked 3 hours and 45 minutes. In the Type list, select h:mm (for hours and minutes), and then select OK. In the Format Cells box, select Custom in the Category list. In cell D2, subtract the end time from the start time by entering the formula =C2-B2, and then press Enter. Type the other start and end times for your friends, Joy and Leslie. In cell C2, enter the end time, including “ a” or “ p” as appropriate, and then press Enter. In cell B2, enter the start time and include “ a” for AM or “ p” for PM, and then press Enter. Here's another example: Let's say that you and your friends know both your start and end times at a volunteer project, and want to know how much time you spent in total.įollow these steps to get the elapsed time-which is the difference between two times. The format will be in the Type list the next time you need it. Take note of the colon after and a semicolon after mm. In the Type box, at the top of the list of formats, type and then select OK. In the Format Cells box, choose Custom in the Category list. Go to Home > Format, and then choose Format Cells. To display the time as more than 24 hours, select cell B4. This is because the time for Task 2 is in 24-hour time. The result is 4:15, which is not what you might expect. Type =B2+B3 in cell B4, and then press Enter.

In cell B2 type 12:45, and in cell B3 type 15:30.

You need to apply a special format to the formula result. Well, that was easy enough, but there’s an extra step if your hours add up to more than 24. Press Enter to get the same result, 16 hours and 15 minutes. Select cell B4, and then on the Home tab, choose AutoSum. Tip: You can also add up times by using the AutoSum function to sum numbers.
