Assign timezones to individual availability slots in Cal ID so bookers only see the hours you set aside for their region.
Extended Timezone gives you per-slot control over global scheduling. Instead of one timezone governing your whole day, you decide which timezones can see and book each individual slot. A client can only book a slot if their timezone is one you assigned to it.
When someone opens your booking link, Cal ID matches slots to the visitor:
Location detection — Cal ID reads the visitor’s timezone from their browser or location as soon as the booking page loads.
Rule matching — Cal ID checks the timezone rules you set on each slot.
Filtering — if the visitor’s timezone matches a slot’s assigned timezones, they see that slot converted to their local time. If it does not match, the slot is hidden and you appear unavailable during those hours.
Break the day into separate windows if you want to offer different hours to different regions. Click the plus (+) icon next to the time inputs to add another slot to a day.

Click the blue Save button in the top-right corner to push the changes live.
Assign timezones slot by slot rather than day by day. A single weekday can carry one window for a domestic audience and another for an overseas one.
