Multiple calendars, scheduled as one.
When your week is spread across three or four calendars, scheduling means checking them all before you say yes. BookTime merges every calendar into a single view and one booking link — so multiple-calendar scheduling finally feels like one calendar.
The short answer
BookTime is built for multiple calendar scheduling: it connects Google, Apple, and Outlook, merges them into one conflict-aware view, and builds your booking availability from all of them. Every account is read together, so nothing you offer clashes with a commitment on another calendar.
Every calendar, one schedule.
The scheduling tool for people whose week doesn’t fit in a single calendar.
One unified view
Google, Apple, and Outlook merged into a single, colour-coded week — every commitment across every account in one place.
Unified calendar →Connect unlimited calendars
Add as many Google, Apple (iCloud), and Outlook accounts as you run and BookTime keeps them in sync in near real time.
Calendar sync →Availability from every calendar
Your booking link is built from your whole schedule, not one calendar — so people only ever see times you’re genuinely free.
Booking pages →No cross-account double-booking
A slot taken on any calendar is instantly unavailable everywhere else. You decide what counts as busy, per calendar.
Blocking rules →Many calendars. One schedule.
BookTime becomes the single source of truth across every calendar you run — so scheduling stops meaning cross-checking three apps.
Multiple calendar scheduling, answered.
What is multiple calendar scheduling? +
It’s scheduling that accounts for every calendar you run at once, instead of one. BookTime connects Google, Apple, and Outlook, merges them into a single view, and builds your booking availability from all of them together. It’s also the main reason people look for an alternative to Calendly for multiple calendars.
How many calendars can I connect? +
As many as you run, across Google, Apple (iCloud), and Outlook. BookTime keeps them in sync and merges them into one conflict-aware view.
Does it stop clashes between calendars? +
Yes. A time taken on any connected calendar is instantly blocked everywhere else and on your booking link, so two things never land in the same slot.
How much does it cost? +
Free during beta, then a flat $8/month — not per calendar — so adding more calendars never costs more.
