Many developers use Experience Events as a means to notify their playerbase for updates and similar events; however, needing to set a specific date for an event can be very annoying when you aren’t sure of when to release something, and will instead either opt not to make an event at all until it’s close to its release or one with an unrealistic placeholder date.
(For example, if you work on a big update for over a month only to create the event 2 weeks before the update, I have had similar experiences like this.)
This is why I think a placeholder date, such as “TBD”, would be a nice addition that allows developers to provide a clearer vision of an experience’s future occurrences and obtain further engagement for their events.
