# Scheduling a One-Time Group Event (Webinars & GDs)

In **Cal ID**, combine **Offer Seats** with availability rules to host a one-time event — a webinar or group discussion — so many people can book the same time slot.

| Why use this setup

* **Host large groups:** many guests join a single session.
* **Lock in a time:** the event happens only when you want, hiding your other availability.
* **Control capacity:** cap the number of attendees.

| How to set it up

|| 1. Enable group seating

1. Open **Event Types**, select the event, and click **Edit**.
2. Go to the **Advanced** tab.
3. Toggle **Offer seats** **ON** and enter the number of participants (e.g., 50).

|| 2. Pick the date

1. In the **Limits** tab, find [**Limit future bookings**](https://help.cal.id/en/article/limit-future-booking-to-restrict-the-future-booking-qwjs4o/).
2. Choose the specific date or date range — this hides all other days so guests only see the event day.

|| 3. Set the exact time slot

1. Open the event type's [**Availability**](https://help.cal.id/en/article/how-to-set-availability-for-an-event-type-12ngw5m/) tab and click **Edit**.
2. Add a [**Date Override**](https://help.cal.id/en/article/date-overrides-or-set-unavailable-1gvl0sc/) for the event day.
3. Set the specific start and end time (e.g., 3:00–4:00 PM).
4. For multiple sessions the same day, add more time ranges to the override.
5. Click **Save**.

| What the booker sees

* **Limited calendar:** most dates are greyed out — only your chosen date(s) are clickable.
* **Specific slots:** only the times from your Date Override appear.
* **Seats remaining:** the page can show remaining seats, adding urgency.
* **Confirmation:** on booking, the seat count for that slot drops by one.

| 💡 Tip

Because you set a date range in **Limit Future Bookings** and a **Date Override** for the time, all seats funnel into one specific slot — a clean, locked webinar setup everyone joins at once.
