I would like to schedule a battle for Zone 36 on Staturday/Sunday
Ok, I'll schedule a battle for zone 38 after that.
I propose:
Zone 36, Saturday 14, 18:00 to 18:30 UTC
Zone 38, Saturday 14, 19:30 to 20:00 UTC
On Saturday, I'd prefer to end them before 21:00 UTC.
If you want them on Sunday, they'll have to end before 19:30 UTC.
They don't have to happen on the same day.
