If I have a total of 400 unique clients in January and it grows to 800 unique clients in October, how can I get a count of how many distinct clients were added for each month?
Ex.
Jan - 400
Feb - 43
Mar - 61
Apr - 31
May - 55
Jun - 49
Jul - 65
Aug - 33
Sep - 30
Oct - 33
800 total
My data set starts in January and I will add to it at the end of each month. It is a list of services and dates, so a client can have multiple services in different months.
Thank you!!
