The agency's business hours and calendar parameters are **agency-wide** settings, not personal ones: only an Admin can configure them, from **Settings → Business hours** and **Settings → Calendar parameters** (full detail in manual 26 · Settings and integrations). They're explained here so you understand where the slots you see or offer on the rest of this screen come from. **Business hours** (Settings → Business hours): an Open/Closed toggle for each day of the week, with its start and end time range when open. For example, the agency is open Monday to Friday from 09:00 to 19:00, Saturday from 10:00 to 14:00, and stays closed on Sunday. Below that there's also an **"Outside hours message"** field, the text a web chat visitor sees when they write outside those hours. **Calendar parameters** (Settings → Calendar parameters): five numeric fields that fine-tune how slots are generated. | Parameter | What it controls | | --- | --- | | **Slot duration (minutes)** | How long each slot the agent offers for an appointment lasts. | | **Buffer between appointments (minutes)** | Free time automatically reserved after each appointment, before the next one. | | **Minimum notice (hours)** | How much minimum notice, from now, an appointment can be booked with. | | **Maximum days ahead** | How many days into the future appointments can be booked. | | **Reminder lead time (hours)** | How much notice would be given before an upcoming appointment. | > **Note — The automatic reminder isn't active yet** > > The screen includes the "Reminder lead time" field, but automatically sending appointment reminders isn't > active yet — the interface itself says so right next to the field.
