To see this for your self, enter the date April 6, 2021. Excel will show it as proven in Determine A as a result of that is the default date format. Don’t fret when you see one thing a bit completely different since you is likely to be working with a special default (if somebody modified it). To the fitting is identical date entered the identical method, however the format is completely different; I modified it to Normal so you may the saved serial worth. If you enter a date string, Excel codecs it as a date utilizing the date format, d-mmm-yy.
The date is an integer; time is a decimal worth. A day equals 24 hours. Twelve hours is half a day, or 0.50. For a complete breakdown, see Desk A. Within the following sections, you may be working with full serial values—dates that embody each a date and time.

Methods to extract the date in Excel
You will usually work with date values that haven’t any decimal worth or time values. When the 2 are mixed into one worth, similar to 44292.0412, they are often tough to work with. For instance, 44292.0412, 44292.0413, and 44292.000695 aren’t the identical worth, regardless that they share the identical date. Determine B exhibits three mixed serial values. Once more, I entered the dates as literal date strings within the first column. To show the serial values, I utilized the Normal format to column C.
Column D incorporates the straightforward operate
copied to the remaining cells. As you may see, Excel applies the Normal format routinely and returns solely the integer portion of the mixed serial worth in column B. You is likely to be questioning why I did not use INT(). You possibly can, however TRUNC() returns solely the integer digits; INT() rounds a quantity right down to the closest integer. As a result of we’re working with optimistic dates values, it will not matter, however destructive dates are potential, so TRUNC() is the safer route.
Methods to extract the time in Excel
Coping with time is usually tougher than coping with dates. Nonetheless, on this case, it is almost as easy utilizing the TRUNC() operate. Determine C exhibits the results of utilizing the straightforward expression
and copying it to the remaining cells. In a nutshell, this expression subtracts the integer portion (the date) from the mixed serial worth. For instance, the expression in E3 evaluates as follows:
MOD() can be utilized, however TRUNC() evaluates solely the precise parts: the integer and the decimal. At this level, you may see the serial values that signify the date and time, however you do not see the precise date and time strings that make sense to you.
Methods to add the formatting
The serial values do not make sense to the viewer, so let’s format columns C and D, so that they show one thing significant. First, choose D3:D5, right-click the choice and select Format Cells from the ensuing submenu. Within the ensuing dialog, select Date from the Class record. (You can additionally use the Format dropdown within the Quantity group.) The Kind preview will replace accordingly with examples. Select the format that fits your wants, similar to Wednesday, March 14, 2021, as proven in Determine D. Subsequent, choose E3:E5, right-click, select Format Cells and select Time from the Class record. Select 1:30:55 PM from the Kind record.
Determine E exhibits the outcomes of formatting each columns of extracted serial values. The formatted values match completely to the mixed serial values. We did not lose or add a factor. All we did was extract the integer and decimal values from the serial values in column B
