Time Zones in Appointments

Every calendar in the Appointments module has its own time zone (your account's by default). It's the reference used to interpret that calendar's business hours, available slots, and already-booked appointments.

How it's used

• The business hours you set (e.g. 9:00 to 18:00) are always understood in the calendar's time zone, not in the browser time zone of whoever is looking at the screen.
• When someone looks up available slots — from the Agenda, the public booking link, or the text/voice AI agent — the times shown are already converted into the calendar's time zone.
• Internally, every appointment stores its start and end time as an absolute instant (regardless of where anyone happens to be), so overlap checks are always correct, alongside the reference time zone used to display it properly.

Configuration

You set the time zone when creating or editing a calendar. Every service and appointment on that calendar inherits it, unless a different one is specified for a particular booking.

Example

A calendar is set to Ecuador time (UTC-5). A customer in Argentina (UTC-3) books a 10:00 slot: that 10:00 is always Ecuador time, not Buenos Aires time, because the time zone belongs to the calendar, not to whoever is booking.

Tips

• If you serve customers across several countries but your team is all in one place, keep the calendar's time zone fixed to your team's, and always state the time zone in the confirmation message.
• If you have teams in different countries, create a separate calendar per time zone for each one instead of mixing everyone into a single calendar.

Troubleshooting

If a customer says "the appointment showed up at a different time than we agreed," check that calendar's configured time zone — it's the real reference, regardless of which clock each person happens to be looking at.
