==========         =======       =======
01-01-2020            3            127.0.0.1

02-03 2020            3            22.33.65.22
02-03 2020            5            11.44.55.66

I need to sum every day visits using unique IP to get 3 last months total web Page views using this table ,I mean this results:

January= 3 visits
February = 3 visits
March = 2 visits
