Whatever platform is the easiest/gets the most traffic, I suggest creating a calendar page that shows the current month. Devs, Mods, and Community can submit events and event details (Such as the ongoing haiku contest) that devs/mods can approve to go public. Might want to have a ‘newsletter’ opt in so people can get auto-reminded of upcoming events. This way there’s an obvious base repository for things with hard dates. ( I have seen the Discord event banner, but I still would like a traditional calendar page.)
