FAQ
What should I do if DATEDIF returns #VALUE!?
- Check whether the parameters use valid date values or recognizable date content.
- Check whether the referenced cells contain extra spaces or text characters.
- Clean the data if needed, then enter the DATEDIF formula again.
Why does the DATEDIF result look different from what I expected?
- Check whether the referenced start date and end date are correct.
- Check whether the cell format affects how the result is displayed, and switch to a general or number format if needed.
- Use formula checking tools on the Formulas tab to review the calculation step by step.
How can I use DATEDIF in multiple cells at once?
- Enter the DATEDIF formula in the first target cell and confirm that the result is correct.
- Select that cell, move the pointer to the fill handle in the lower-right corner, and drag downward.
