Events in Forsaken World range from daily events to weekly events and more. You can find out which events are occurring by opening the event schedule window by hitting the "U" key. This window will display all of the day's events, both past and present.
You can always check the server time by hovering your mouse over the lower right corner of the mini-map
To join an event, you will need to either travel to the place where it begins, or use the auto queue system ("T" key) to find a group for the event you want to participate in.
The auto-queue system pairs you up with the best available players to form a group. It's a great way to jump into a dungeon or event without having to spend hours looking for a group in the world chat channel.
