Method 3 – Utilizing the IF Function
To use the iterative formula you need to do the following changes in Excel options
Enable Iterative Calculations:
First, go to File > Options > Formulas.
Then, select Enable iterative calculation.
Steps:
- Insert the following formula in cell C5.
=IF(B5<>"",IF(AND(C5<>"",CELL("address")=ADDRESS(ROW(B5),COLUMN(B5))),NOW(),IF(CELL("address")<>ADDRESS(ROW(B5),COLUMN(B5)),C5,NOW())),"")
- Hit Enter and use the Fill Handle option to apply the formula to all desired cells.
- If you put values in column B, then you will get the results in column C.
How Does the Formula Work?
- ADDRESS(ROW(B5),COLUMN(B5)),C5,NOW())): This portion represents the reference cells.
- NOW(),IF(CELL(“address”)<>ADDRESS(ROW(B5),COLUMN(B5)),C5,NOW())): this portion represents the selected range of the cell with conditions.
- IF(AND(C5<>””, CELL(“address”)=ADDRESS(ROW(B5), COLUMN(B5))): This portion represents the conditions within the defined reference cells.
How to Use the Date Formula in Excel
Steps:
- Insert the following formula in cell B5.
=DATE(1999,1,1)
- After pressing the Enter button, you will get the result for this cell.
- If you insert the desired dates individually in column B, you will get the results in column C.

Things to Remember
- For the IF Function, if you are a Microsoft 365 user, you only have to press the Enter button to run the formula. Otherwise, you have to press the Ctrl + Shift + Enter buttons.
