Organise a weekly game night on Discord
A game night works when it is a habit, not a negotiation. With when? you pick the people once, and the next night starts by itself.

1. Invite the right people
Create the event and tick the members of your server, or a whole Discord role at once. Mark the ones who must be there as required.

2. Let calendars do the work
Guests can link their Google, Outlook or iCloud calendar: one click marks as busy the times when they already have something.

3. Make it repeat
Choose every week, every 2 or every 4 weeks. Once the night is over, the next one is created by itself with the same guests, the dates moved on.

4. Let the bot remind everyone
The bot sends the date by private message, creates the Discord event and reminds the ones who have not answered. Everyone adds it to their own calendar in one click.
Set it up once and the game night runs itself. Free, no account to create.
