Dokkan Events appear weekly. Except the new ones. They are added to the rotation later on. You can check Dokkan Events rotation which is when.

Global does follow the japanese rotation but not always exactly the same. It does help in the long run but sometimes events get pushed sooner or even later then they're expected to. For example the EZA of Super Gogeta should of been after Beerus and Super Saiyan 3 Vegeta but got pushed forward due to the Broly movie.
