Multiple calendar sync
Every calendar, always in sync.
Connect as many Google, Apple, and Outlook accounts as you run. Book a meeting anywhere and it shows up everywhere within seconds — no more forgetting which account an invite landed on.
Connected calendars · all in sync
Why it matters
The problem isn’t your calendars. It’s that they don’t talk to each other.
Every account keeps its own version of your week. BookTime connects them so a change in one is reflected in all of them — the foundation your unified view and booking pages are built on.
How sync works
Connect once. Stay in sync.
Everything flows through automatically after the first connection.
Unlimited accounts
Connect as many calendars as you like across Google, Apple, and Outlook — including several accounts from the same provider.
Providers
Near real-time, two-way
A meeting booked on any connected calendar appears across all of them within seconds — and bookings made in BookTime flow back out.
Just now
Set it and forget it
Once connected, sync runs continuously in the background. You never have to refresh or reconcile calendars by hand.
