This could be a dumb question and I must be missing something, but I am confused with the battle pass season length.

I see daily challenges for 100 days, and 100 days of gold weekly dailies. So, I assumed a season would last 100 days. However, the season length in the weekly shows 8 weeks = 56 days, and there are 8 weekly challenges. There is a count down too, now it says 7w5d.

So, which is the exact Battle pass season length? I mean, it can be 100 days of a season, weeklies could just ends before the end of the season. Or a season itself ends after 56 days, and we have to buy another Gold pass to get level 100 rewards?
