I am a Field Sales rep and I have an excel report of what hospitals I went to on what days.

I'm trying to make a heat map using conditional formatting to visualize time passage regarding who I haven't visited recently. I'm using the below formula to pull up the visit date minus today's date which works well for the heat map:

=(Sheet3!$A$4-TODAY())

This works with business that show up a single time in my report (one visit, like "Happy Tails Hospital" below). However, here is where I'm hitting a snag: If I visited a business multiple times recently, it will show up as multiple entries (like "Claws and Paws" below). When there are multiple entries, I need a way to have the formula use the newest date for that business to calculate the time passage. So for Claws and Paws, I would need it to apply the 3/5/2020 date to the "heat map" formula from the Raw data sheet.

Will the fill handle fill 1, 2, 3?
Yes! Type 1 in a cell. Hold down Ctrl while you drag the fill handle.

Try -
Change the sheet name to match yours

=MAX(IF(Raw data sheet$B$2:$B$9=A2,Raw data sheet$A$2:$A$9))-TODAY()

Enter as an array with Ctrl, Shift & Enter
