For me, in Australia, TBT is very inactive from 8pm onwards. (I nickname it the dead time).
On weekdays, It's usually active in the morning & afternoon up to 5pm for me in Australian time. And it is very active at 3-7am (sometimes I stay up super late so that's how I know).
Well it's not active right now
My timezone is GMT -5, which I figured out is either an hour ahead or an hour behind EST
But then there's GMT,PST...ugh words
When I get home from school it's pretty active, but it's also pretty active at like 3 AM my time
