How calendar sync works
Enjoy our set-and-forget approach — we keep your Google, Outlook and iCloud calendars in sync, automatically.
2-minute setup
Copy your free/busy times across your calendars in real time
Connect your Google, Outlook or iCloud calendars, choose a source and a target, and you're all set — we handle copying every upcoming event for you.
One-way or two-way syncs
Multi-way calendar sync direction
Choose whether your calendars mirror events both ways, or only copy from one to another. It's entirely up to you.
Privacy focused
Keep control of your event details
Hide the details of any field in the copied event — title, description, location and more — behind a simple 'Busy' block.

I absolutely love being able to sink my calendars so that I am not overbooking myself, as a stay at home mom, active member of my church and running two small businesses it sometimes gets very hectic keeping up with my own schedule and switching between calendars can be overwhelming this is a game changer!
Neicee Sweet Google Workspace Marketplace It actually works. I needed to sync my outlook calendar to my google calendar. I tried a free way to do it, but it wouldnt show up on my phone calendar so that was a waste. This was super simple and it did sync seemlessly with both deskptop and phone google calendar.

FAQ
Frequently asked questions
What does SyncThemCalendars exactly do?
It keeps two or more of your calendars in sync by automatically copying events between them — filling a gap that leading services like Google Calendar leave open.
Why do I need calendar sync?
Common cases: managing multiple client calendars, running several businesses, or blocking your personal time on a work calendar so colleagues can't book over it — without revealing what it is.
Is it free?
You get a 14-day free trial with no credit card required. After that, a paid subscription keeps your syncs running.
What calendar providers are supported?
Google Calendar, Microsoft Outlook / Office 365, and Apple Calendar (iCloud). You can sync across any combination of them.
Will you use my data?
Your data is only ever used to copy events across your calendars. We never sell it or use it for anything else.
