You set when a participant can join a session.
How to set it up
- Creator → Schedule.
- In Webinar type choose:
- Continuous (evergreen) - available dates / slots,
- One-time - a single event date,
- Watch now - starts right after registration (separate page: Watch now).
- Fill in dates / slots for the selected type.
- Webivio uses participant time zones when matching a session.
Slots in continuous (evergreen) mode
In Fixed webinar hours you add slot rows. Each slot has:
- Time - session start (15-minute steps),
- When to show - Every day, Selected weekdays, or Selected days of the month,
- Days (optional) - specific weekdays or month days when the matching mode is selected.
You can also enable Automatic sessions (JIT) if you want the system to propose upcoming sessions in a time window.

How time zones work
The registration page detects the attendee's IANA time zone from the browser (for example Europe/Warsaw). Sessions are calculated and displayed in that zone, while UTC time and the attendee's zone are also stored. This lets the same session appear in local time to people in different countries.
When registering through the API, send a valid userTimezone. If it is missing or invalid with the instanceDate + instanceTime variant, the code falls back to Europe/Warsaw. See the Registration API.
