Clash schedule question

Hello,

I was a little confused if we play tonight. If you look at the attached picture in the link, it says we play December 8th from 8-10 PM, so do we not play tonight (Saturday)? If we do play tonight, do we only have until 10:00 PM tonight to lock in? I know you have until 10:00 PM on Sunday, but is Saturday different since it starts 30 minutes later (In the picture, it says it starts at 8:30 PM)?
