Understanding the difference between time intervals and minimum reservation length is important — they control two very different things in Birrdi.
Time Interval (15, 30, 60 minutes)
The time interval determines how your entire schedule is structured.
It controls:
The time slots customers can book (e.g. every 15, 30, or 60 minutes)
How all rates are calculated
How availability is displayed across your calendar
Examples:
15-minute interval → bookings at 10:00, 10:15, 10:30, etc.
30-minute interval → bookings at 10:00, 10:30, 11:00, etc.
60-minute interval → bookings at 10:00, 11:00, 12:00, etc.
Changing your time interval impacts your entire system and requires backend updates.
Important:
When you change your time interval, your rates must also be updated to match the new interval.
For example:
Moving from 30 → 60 minutes means your rates must be converted to hourly pricing
Moving from 60 → 30 minutes means your rates must be split into half-hour pricing

Minimum Reservation Length (e.g. 1-hour minimum)
The minimum reservation length controls the shortest booking a customer can make.
It does NOT change your schedule — it only sets a booking rule.
Examples:
30-minute interval + 1-hour minimum → customer must book at least 2 time slots
15-minute interval + 1-hour minimum → customer must book at least 4 time slots
This is a flexible setting you can update at any time.

Key Difference
Time Interval = how your schedule is built and requires rate updates (paid change)
Minimum Reservation Length = booking rule on top of your schedule (free setting)
When Should You Change Each?
Change Time Interval if:
You want a completely different scheduling structure (e.g. move from 30 → 60 minutes)
Use Minimum Reservation Length if:
You want to require longer bookings (e.g. minimum 1 hour)
You want to keep flexibility without changing your entire setup
