Monthly sale schedules?

I remember there was one or two months where you guys put up a schedule of the sales that were going to happen over a period of time and i LOVED it. I like being able to look ahead and see if i should save money to buy riot points or just hope i can scrounge money together when a skin I really like goes on sale. I loved it because I could also see if i should save my left over riot points for the really cool skin that I've wanted for a long time now that might go on sale next week or buy this one i don't really care that much about and hope i don't miss out on one i like a lot more. I don't know if it was a seasonal thing that you guys were doing or if it was a summer thing. I honestly can't remember but all i do remember is that i loved it and i kind of want that to become more of a regular thing and want to see if anyone else agrees with me.
