Features
Everything a team needs to share a calendar, inside Slack.
A Slack calendar app built around the way teams already work — channel-scoped calendars, Slack event cards, automatic Slack calendar reminders, an App Home agenda, OOO tracking. The team calendar app for the channels your team is already in.
Join waitlistCalendars
Channel-scoped calendars built for the team that lives there.
Every Scalendar calendar belongs to a Slack channel — scoped to that channel, with the same membership and the same audience. Public channels, private channels, multi-team channels — they all work the same way: the shared team calendar lives where the decisions happen, and everyone in the channel sees the same dates at the same time.
- The right audience, automatically. Channel membership equals calendar membership — events go to the people who care, nobody else. In a private channel calendar, only the people in the channel see the events.
- Formal calendars and free-for-alls, side by side. Lock the release schedule down so only leads can edit it, then let the whole channel chip in on team rituals — same product, two postures.
- Onboarding new joiners is automatic. The moment someone joins the channel, they see what's already on the calendar — no "here's the link" message, no separate handoff.
Events
Slack event cards for everything a team plans together.
Standups, launches, leave days, demos, all-hands — the things teams actually need to plan around. Every event you add lands in the channel as a Slack event card the whole team can see, the moment it's created.
- Color-coded event categories. Tag events by type — launch, ritual, leave, social — and let the colour-coding tell the team what the week actually looks like at a glance.
- Multi-day events that span the actual window. Off-sites, code freezes, conferences, week-long OOO — give an event a real start and end and it takes up the actual window on the calendar.
- Always know who put it there. Every event card shows its creator, so follow-up questions go to the right person instead of into a thread nobody reads.
Reminders
Slack calendar reminders the team can't miss.
Slack event reminders post in the channel before every event — automatic, default 15 minutes before, tuneable per event. No standalone reminder bot, no human in the loop, no more missed meetings because someone forgot to send the ping.
- Sensible defaults out of the box. A reminder 15 minutes before every event, posted in the channel — whether you set it up or not. Change the default per calendar, per event, whenever.
- Stack as many as you like. 1 day before, 1 hour before, 5 minutes before — match the rhythm of the event, not someone else's defaults.
- Personal DM pings (coming soon). Opt-in private nudges on top of channel reminders — for the events you genuinely can't miss.
Slash commands
Schedule it the moment you think of it, right where you're already typing.
Type a Slack calendar command in any channel and the work happens — no menus to dig through, no separate app to load. Capture plans the second they come up, before they fall out of someone's head.
-
/calendar create— start a fresh calendar in the channel you're already in. -
/calendar add— drop a new event in under thirty seconds. -
/calendar view— see what's coming up, filtered to this week or this month. -
/calendar help— forgot something? we've got you.
App Home
A unified calendar view in Slack — every channel, one App Home agenda.
The Scalendar Home tab in Slack rolls up every channel calendar you can see — sorted, dated, ready to click. A unified calendar view, with no hunting through channels to find the next meeting.
- Your next seven days, all at once. Every channel calendar on one App Home agenda, sorted by when things happen.
- One click into any event. Jump straight to the channel and conversation — no scrolling sidebars, no remembering names.
- Know where you stand. Plan and usage on the same screen — no digging through settings to see how many calendars you've spun up.
The rest of the kit
All the bits you'd expect, plus a few you wouldn't.
Annual leave & OOO tracking
A Slack out-of-office calendar in any channel. See who's off, when, and for how long. Multi-day events render across the full date range — a team OOO tracker without the spreadsheet.
Color-coded event categories
Tag events by type, then filter the channel's calendar by tag. The cleanest possible weekly roll-up.
Permissions that fit your team
Creators edit their own events. Channel admins edit any. No accidental overwrites, no untraceable changes.
Recurring events
Schedule daily, weekly, or monthly cadences once. The calendar handles every instance after — including the exceptions when life happens.
RSVPs
Know who's actually coming before the meeting starts. Going, Maybe, or Not Going — one click per event.
Timezone smarts
Every event renders in each viewer's local time. Distributed teams stop doing mental math at the start of every standup.
Event attachments
Zoom link, agenda doc, slide deck — pinned to the event itself. Never lost in a thread, never expired in an invite.
Event threads
A dedicated discussion thread on every event. Decide before the meeting, capture decisions after — same place every time.
iCal export
Drop your team's events straight into people's personal calendars. Two-way sync with Google & Outlook on the roadmap after.
One install. Every channel. Zero new apps.
Add Scalendar to your Slack workspace and run /calendar create in any channel.
That's the entire setup — your team's shared calendar lives there from then on.
