How do you add 20 minutes to a time value in Microsoft Excel?
What is the difference between a time value and a date & time value?
There’s a lot of confusion about data and time values in Excel but it’s easy to learn!
A date value is an integer (i.e. a number without decimal values like 42241).
A time value is a decimal (i.e. 0.5 = noon. Closer to midnight looks like this 0.94).
We format these values to make them look like readable date and time values:
- 25/08/2015 = 42241 Date without a time value
- 12:00:00 PM = 0.5 Time without a date is a fraction of 1 day
- 25/08/2015 12:00:00 PM = 42241.5 Date & Time (noon on August 25th, 2015)

“Mastering Excel Date & Time Formulas”
by Tim Hill is a quick read and great e-book (google play store).
The book also has a helpful companion Excel file.
