I would like my target completion column to have a date that is greater than my start column. Excel supports a date validation option but I do not see this in Google Sheets.

Is it there and I just don't know how to use it?

I saw this question: Restrict the valid values in one cell, based on the value in another cells but I can't see how to get it to apply to the same row in the other column. Obviously I don't want a new rule on each cell.


Short answer

Yes, Google Sheets can.


  1. Optional. Select the range to apply the data validation
  2. Right click on the selected range or click on Data > Validation...
  3. Optional. Write/edit the range to apply the data validation
  4. Click on Criteria and select Date Data Validation criteria dropdown options

  5. Set the rule options including a formula using the top left cell reference, i.e. =A1

Data Validation date rule after cell value

  1. Click on the Save button.
  • This is good to know but I don't think it solves my problem. I would like to require each cell in column B be after the date in the cell in the same row in column A. That is, B2 must be after A2, B3 must be after A3, etc. Is this possible? – Scott Nov 7 '16 at 17:46
  • That is exactly what the above instructions do. Please follow the instructions, just replace Sheet1!B1 by Sheet1!B:B or something similar. If the above instructions don't work for you create a demo spreadsheet to show what do you tried, share it with anyone with the link and add the link to your question. – Rubén Nov 7 '16 at 17:51
