Conditional Format Formula Based on the Week

Hello all,

I'm working on a Gantt spreadsheet broken down by week to track our tax deadlines. Primarily I track: when the notice is received, the date it's due and the date it's submitted. The Gantt chart works great for this, however, I would like to set an additional conditional formatting rule that will change the format of the cell representing the last full week prior to the due date as well as a second rule that will change any weeks following that due date to a different format.

This way, just by glancing, I can see the last full week I have to meet the deadline as well as any penalties I can expect if the deadline isn't met.

The spreadsheet is attached.

The first tab, "Tax Schedule", is the sheet in good order needing the revision. The second tab, "Example", is a sheet that appears the same as the first, just with notes and arrows listed to explain what I'm looking for.

Any and all help anyone can provide is greatly appreciated. Thank you, Kara

Welcome to the forum!

As many members can't access file-sharing sites, will you please attach a sample Excel workbook?

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired results are also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment, so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.
