Matching and numbering rows


I need help creating a formula that will check 2 columns (Location and Date) then create a number for that row. If on previous rows the same match occurred, then the number will grow.


Number Location Date

1 SLC 2/20/2020

2 SLC 2/20/2020

1 ATL 2/20/2020

3 SLC 2/20/2020

1 SLC 2/21/2020

1 ATL 2/21/2020

2 SLC 2/21/2020

As you can see when location and date match with a previous row, the number is added by one. On this way I can see how many times a Location is checked in the same day.

Thank you. Al
