Excel: Separating Time & Date
By Richard Rost   Richard Rost on Facebook Richard Rost on Twitter Richard Rost on Google Plus Richard Rost on LinkedIn Email Richard Rost

Q: How do I remove the date from a cell with both the date and time (the date seems to show up automatically, although I'm only interested in the time). In short, I want to go from "4/7/2008 6:18:00 AM" to "6:18:00 AM". Thanks, Lauren.

A: Lauren, the only easy way I've found to do this is to break up the date/time into its components (day, month, year, etc.) and then put them back together again with the DATE() and TIME() functions.

For example, let's say A1 has: 4/7/2008 6:18:00 AM

Put the following functions in the next cells:

B1 = YEAR(A1)
C1 = MONTH(A1)
D1 = DAY(A1)
E1 = HOUR(A1)

Now put them all back together:

H1 = DATE(B1, C1, D1)
I1 = TIME(E1, F1, G1)

That's about the only easy way to do it and still keep the value as a DATE/TIME and not text (you could do it with string concatenation too, but you would then have to convert it back to a date).

I have a column with the numbers like SS02. How do I make it look like SS-02 in Excel. Thanks.

I've been struggling with this myself because I have a database that was exporting an elapsed time as a date and time. I figured out the following single cell solution.

Assuming the date and time is in cell A1 use the following formula =MOD(A1,1). You can then format the results with whatever time format you want.

This works because the MOD function computes the remainder after dividing by the number to the right of the comma. In this case dividing by 1 leaves only the numbers to the right of the decimal.

In Lauren's example this leaves a decimal of 0.2565. When formatted with the appropriate time function you get the format Lauren is looking for.

Jim, you can do that with Window > Freeze Panes. I cover it in Excel 103.

Ruby, thank you for the feedback. You are correct... you can apply a custom format like that to VIEW the date or time... but if you want to CHANGE the value (for calculations) so that it's ONLY a date or time, a format alone won't work.

Ramon, the easiest thing to do is to visit the Download Center and download the latest copy of the Amicron Video Player. Then, once you have the Player installed click on the MY ACCOUNT button. Log in to your account and you can download all of your courses right from inside the player.

If the date is showing up automatically when only time is needed, the cells are probably formatted in either DATE or TIME custom format as:

[$-409]m/d/yy h:mm:ss AM/PM;@

and can simply be changed to

[$-409]h:mm:ss AM/PM;@

so that the date does not show.
