How-to Guide

1. Create a formula field and enter EDATE

Entry path: Add Field → Formula.

  1. Open the data table you want to edit.
  2. Select Add Field.
  3. Choose Formula as the field type.
  4. In the formula editor, type EDATE(.
  5. Complete the parameters and save the field.

Success Check

  • What you should see: a new formula field appears and returns a date result.
  • What you can do next: edit the formula or review results across other records.

Notes

  • Common mistake: trying to enter the function before creating a formula field.
  • Limitation: you need edit permission for the current data table.

2. Set the EDATE parameter structure

Entry path: Formula editor → type EDATE(start_date, months).

  1. Enter a start date field or a value that returns a valid date.
  2. Separate parameters with a comma.
  3. Enter the month value. A positive number shifts forward, and a negative number shifts backward.
  4. Close the parenthesis to complete the formula.
  5. Save the formula and review the returned result.

Success Check

  • What you should see: the formula editor shows a complete EDATE parameter structure.
  • What you can do next: change the start date or month value and confirm the result updates.

Notes

  • Common mistake: using a value that is not recognized as a valid date.
  • Limitation: integer month values are generally the clearest choice for stable results.

3. Combine EDATE with other formulas

Entry path: Formula editor.

  1. Identify the date, logic, or text formula you want to combine with EDATE.
  2. Insert EDATE(...) in the outer or inner part of the formula.
  3. Use field references to connect other inputs.
  4. Check the parentheses and parameter order.
  5. Save the formula and confirm the result matches your rule.

Success Check

  • What you should see: the formula field returns the final combined result.
  • What you can do next: reuse the same formula pattern in other fields.

Notes

  • Common mistake: incomplete parentheses in nested formulas.
  • Limitation: it is helpful to verify the EDATE result first before building a larger formula.
