DATEVALUE Function – Google Sheets

The DATEVALUE function takes a date value in any valid format and returns it as a serial number. Spreadsheets store dates and times as serial numbers in Google Sheets, so they work in formulas (you can add March plus June).

You can use the DATEVALUE function to prepare dates to be sorted, filtered, or used in formulas.

The input for this function needs to be either surrounded by quotes or a cell reference.


The DATEVALUE function returns a serial number from any valid date.



  • date_text – The date, written in a text format, for the function to convert

Related functions

TIMEVALUE – Converts a time to a numeric value similar to DATEVALUE

YEAR – Returns the year value from a date

MONTH – Returns the month value from a date

DAY – Returns the day value from a date


#VALUE! – The inputs aren’t a valid date, such as “A minute ago” or “Then.”

#NUM! – An input is a number but is not a valid date.


Example 1 – Plain and Simple

=DATEVALUE("March 1, 2017")March 1, 2017

We have a date-value that Sheets recognizes to return a serial number. In this case, we set the formatting to Date to show the serial number as March 1, 2017. If you set the formatting to number, the result of the function would be 42,795.00.

Example 2 – Unrecognized Text Date

=DATEVALUE("March 1st, 2017")#VALUE!

Secondly, a full date typed as 1st instead of 1 returns a #VALUE! error. The #VALUE! error occurs whenever Sheets cannot figure out the text date.

Example 3 – Just a Day and Month

=DATEVALUE("March 1")March 1, 2022

Just a day and a month typed in. The spreadsheet assumes the date should be the current year when we updated this article in 2022. The year value will always be the present year when viewed in the live spreadsheet.

Example 4 – Used in an employee timesheet

Last, below is an example of this function creating an employee timesheet.

  1. Do you happen to do any consulting work? I’ve learned a ton from your videos but cant quite get a date formula I need figured out. I

    • Basically I’m trying to insert a due date associated with as task with a check mark column next to it, if the check mark column doesn’t get clicked by the due date I trying to get the cell to turn red. Thanks in advance, really love this website.

      • As far as doing it with a pre-made formula – sort of, but not really. You could use a combination of an IF formula, and if the checkmark’s value is TRUE, you could then use the TODAY function. However, the TODAY function updates to the current date every time you open the Sheet.

        You want more of a timestamp. I think that would be a custom script. Consulting, sure. Let me know what you have in mind if you’re still looking.
