Limited-time events are a set of quests or activities which give unique rewards, that you can only participate in during a set time. While there is no set calendar for events, Bioware announces a new schedule each month, so keep your eyes open for upcoming events on the Devtracker!
When do events take place? Some events repeat roughly every month or every two months, while others are only once per year. Most events only last a week, but others last for a month or more, so keep an eye on the start and end dates for any events you want to join!
Who can participate in events? Although events are more aimed towards experienced players, all players can participate in events, including free-to-play players! Some events have a level requirement, while others just require that you have earned your ship in the story so you can fly around the galaxy.
