So, we cleared our doubts about how to calculate time in excel 2016. Since a day has 1440 (24*60) minutes, we multiply the result by 1440 to get the exact number of minutes.įor this example, we write the formula below in cell D2 and copy it in the cells below: =( C2 - B2 )*1440 We subtract time/dates in excel to get the number of days. The Generic Formula to calculate the minutes between two times is: (END TIME - START TIME)*1440 In the next column, you want to calculate the minutes passed since you started that task, as shown in the above image. NOW() in excel is used to calculate the current time. In the next column you have NOW() function of Excel is running that give. You enter the start time of a task whenever you start it. Make your Excel date and time math simple. You just need to subtract the start time from the end time. Well, in excel 2016 calculating the time difference is quite easy. It has over 25 pages (twice that of other books) of information and formulas regarding date and time, and the complete Table of Contents can be previewed (affiliate link).While working with time and dates in excel, you frequently get the need to calculate hours, minutes and seconds between two timestamps.

Otherwise, the OR function is false (neither cell is blank) and Excel proceeds with with subtraction as indicated in the value-if-false argument of the IF function.

If either cell is empty, the OR function is true and the value-if-true argument of the IF function has Excel put an empty string ('') in the cell so that nothing displays in the cell.

The logical-test argument of our IF function contains an OR function which checks the cells in both columns B and C, using ISBLANK, to see if either cell is missing a date.

=IF( logical-test, value-if-true, value-if-false). The IF function performs a test and provides a value depending on if the result is true or false. Using a simple subtraction formula results in a horrible looking worksheet! Only cells D4 and D7 have meaningful results. In our sheet below, either date might be missing depending on machine requirements. How to Subtract Dates if Either Date, or Both Dates, Could be Blank We have tutorials that clearly explain how and when to use some of Excel's most popular and useful functions.

If there is a Completion Date, then the logical test with ISBLANK is false, and the value-if-false argument tells Excel to proceed with the subtraction as we can see in cells D5 and D7.

If it is, ISBLANK returns a value of true and the value-if-true argument of the IF function tells Excel to put an empty string in the cell (double quotes '').

The logical-test argument of the IF function contains an ISBLANK function testing to see if the Completion date is blank.

For example, to get the difference between the times in A2 and B2, use this formula: A2-B2. The formula for subtracting time in Excel is built in a similar way: Endtime-Starttime. =IF( logical-test, value-if-true, value-if-false) How to add and subtract dates in Excel How to calculate days between dates in Excel How to subtract time in Excel. The IF function of Excel performs a test and provides a value depending on if the result is true or false. Our revised formula is =IF( ISBLANK(C4), '', C4-B4).
