Creating a Tickler for a Date + 180 Days in Excel

1. Select the cell where you want to enter the starting date. Let's say it's cell A1.
2. Enter the starting date in cell A1.
3. In the cell next to it (let's say cell B1), enter the formula
   Code:

   =A1+180

   . This will add 180 days to the starting date.
4. Now, select the entire column where you want to create the tickler. Let's say it's column B.
5. Go to the Home tab and click on Conditional Formatting New Rule.
6. In the New Formatting Rule dialog box, select "Use a formula to determine which cells to format".
7. In the formula bar, enter the formula
   Code:

   =B1<=TODAY()

   . This will check if the date in cell B1 is less than or equal to today's date.
8. Click on the Format button and choose the formatting you want to apply to the cells that meet the condition. For example, you can choose to highlight the cell in red or add a border around it.
9. Click OK to close the Format Cells dialog box.
10. Click OK again to close the New Formatting Rule dialog box.

Note: This will serve as a tickler to remind you that 180 days have passed since the starting date in column A.
