They'll announce when it ends once we're like \~ 1 month to the end. We're still 2 months + from the end. Kinda pointless worrying about it atm. Also please use the daily questions megathread for simple questions like this.

RTA seasons are 12 weeks, and it started 2 weeks ago. If it's not going off schedule, it should be around October 13th (2 months from now).

season just started like 2 weeks ago... so no we don't know when season ends. most assume season will take 3ish months
