I am sure this might be an easy one as I refer to this site often and helps me out a lot!
I have large data that comes in with number of occurrences by date. What I am trying to do is try to find trends faster by counting the number of occurrences within the first 30 days of first occurrence. For example if the first occurrence happened Sep 1, and there were 3 more in September I would like to have this output for this particular Item in a separate column. See below for example of how I would like it to look. The first table is an example of data that I look at. The next table would be a separate table of a report I would like to see out of the data. Any ideas on how to create something like this?
