About CalCrony

CalCrony turns your Discord server into a scheduling machine — events with one-click RSVP buttons, recurring series, time polls, availability grids, and calendar sync, all from slash commands, plus a full web app over the same data.

📅 Events — /create with natural-language times ("tomorrow 6pm", "3rd Friday"), rich embeds, live-updating RSVP lists, event discussion threads, and automatic attendee roles for everyone who RSVPs "Going."

🔁 Recurring series — every-N days/weeks/months (by date or nth weekday), timezone-aware across DST, rolling next occurrence, skip/stop/revive, per-occurrence or whole-series edits.

⏰ Reminders & notifications — one-off /remind, up to 5 scheduled pings per event, automatic start announcements, crash-safe delivery.

🗳️ Polls & time polls — up to 10 options, single- or multi-vote, anonymous mode, voter-added options, auto-close deadlines — and a time poll's winning slot converts into a real event with one click.

📆 Calendar sync — a per-server ICS subscribe URL for Google/Apple/Outlook (recurring events include their full schedule), opt-in mirroring into Discord's native Events tab, and Google Calendar free/busy availability grids (least-privilege scope: CalCrony never sees your event details).

🌐 Web app — sign in with Discord at calcrony.app: create/edit/RSVP from the browser, manage series and notifications, five interface themes, mobile-first.

Free, open source (MIT), no premium tier, no tracking. Self-host it if you'd rather keep your data on your own infrastructure: github.com/JJWren/CalCrony · Docs · Support server

First steps after inviting: /settings server-timezone, then /settings default-channel.
