Store owners/ event organizers- how far in advance does newtype applications open for silver+ stores

Basically the subject.

Trying to help a local store get on board with newtype events. They’re currently silver.

I have experience with instant events and event application tab but it was for a bronze store so I don’t know how far ahead newtype applications come up.

I know i did stuff for October release probably early May so it’s 5 or so months. Anyone know so I can tell them when to keep an eye out and stay on top of event applications?

Thanks so much!!!
