I have a .csv document containing a list of 40 000+ contacts for which I have the list of the moment they were contacted (by email) in a date; hour format (i.e 2017-01-17 12:02:00)
Example
contact 1 2018-09-15 14:02:00 2017-01-17 12:02:00
contact 2 2016-02-17 02:03:00 2016-03-17 04:32:00 2017-11-14 08:42:00
What I'm trying to do is to count the number of time a contact has been contacted in a given day or week. Ideally, be able to know
- Max number of time a contact has been contacted per day/week during the selected period
- Average number of time a contact has been contacted per day/week during the selected period
A bit like this: Count number of times a date occurs and make a graph out of it
Except I have not just one list of dates but more or less 40 000
Thank you all!
