What do slot duration, slot interval, buffer and the other availability settings mean?

Created by Valerie VanBooven, Modified on Sat, 14 Nov at 4:27 PM by Valerie VanBooven

Each calendar has a handful of settings that decide which times families and referral partners can book. Getting these right prevents back-to-back assessments with no drive time and stops last-minute bookings you cannot staff.

The settings explained

SettingWhat it controlsHome care example
Slot DurationHow long each appointment lasts.60 minutes for an in-home assessment.
Slot IntervalHow often a new start time is offered.Every 30 minutes, so 9:00, 9:30, 10:00.
BufferProtected time before or after each appointment.30 minutes after each visit for driving to the next home.
Appointments per SlotHow many people can book the same time.10 for a family caregiver information session.
Appointments per DayThe most appointments allowed in one day on this calendar.4 assessments per day per coordinator.
Minimum Scheduling NoticeHow far ahead someone must book.24 hours, so you have time to prepare.
Date RangeHow far into the future someone can book.4 weeks out.
Office HoursThe hours when booking is allowed.Monday to Friday, 9 to 5.
Event ColorThe color of these appointments on your calendar.Green for assessments, blue for referral meetings.

How duration, interval and buffer work together

  • Open 9:00 to 11:00, 30-minute duration, 30-minute interval: slots at 9:00, 9:30, 10:00 and 10:30.
  • Same hours, 30-minute duration, 15-minute interval: slots every 15 minutes from 9:00 to 10:30.
  • With a 15-minute buffer after each appointment: if someone books 10:00 to 10:30, the next open slot is 10:45.

Common questions

  • Can I set different buffers or date ranges for different appointment types? Not on one calendar. These settings apply to the whole calendar. Create a separate calendar for each appointment type that needs different rules.
  • Can I change the slot interval for certain days? No. It applies to all open hours. Use a separate calendar if one day needs a different rhythm.
  • Does Appointments per Day count across all my calendars? No. It counts per calendar only.
  • Will changing a setting affect appointments already booked? No. Changes to duration, notice, office hours and the rest apply only to new bookings. Existing appointments stay as they are.
  • Can more than one person book the same time? Only if Appointments per Slot is set higher than 1.
  • Can I use buffer for drive time? Yes. This is one of the best uses for it with in-home visits.

If time slots are missing even though your hours look right, also check your Schedule, blocked off time and any conflict calendars connected to your profile.
