Hi
I want to start formatting on the first short date in the column and repeat each 5th day see example * dates marked yellow background

08-Nov*
09-Nov
10-Nov
11-Nov
12-Nov
13-Nov*
14-Nov
15-Nov
16-Nov
17-Nov
18-Nov*
19-Nov
20-Nov
21-Nov
22-Nov
23-Nov*
If I use the following formula the return is partly correct but I cannot get it to start on the nominated date
Is what I want possible
