One calendar view for work and private life
Merge all your appointments into one calendar.
Most people have a work calendar, a private calendar, and sometimes more calendars from clients or side projects. Finding a free slot becomes messy. Sync Calendars copies your appointments into the calendar you actually use, so you only need to check one place.

The problem
Scheduling breaks when your life is split across calendars.
You check the wrong calendarA free slot in Outlook is not really free if your private Google calendar is already booked.
People book over your private timeAppointments outside your work calendar stay invisible to colleagues and clients.
Finding a slot takes too longYou switch between calendars, compare availability manually, and still risk double bookings.
The solution
Choose one calendar as your source of truth.
Pick the calendar you want to live in every day. Sync Calendars brings appointments from your other calendars into that one calendar as private blockers, title-only events, or full copies.

How it works
Connect accounts, pick your main calendar, decide what gets copied.
Choose the main calendar
Select the calendar you want to check every day. This becomes your calendar hub.
Add the other calendars
Create rules that copy appointments from work, private, client, or side-project calendars into the hub.
Control privacy
Copy only busy blocks, copy titles with prefixes, or copy selected details when you need them.
Configuration
Everything you need to build one reliable calendar view.
Merge calendars into one hub
Copy events from Google, Outlook, Microsoft 365, client calendars, and side-project calendars into one destination.
Private blockers
Show that you are busy without exposing title, guests, body, location, or meeting links.
Smart filters
Skip free, tentative, declined, private, all-day, or category-tagged events.
Changed events stay aligned
When source meetings move or disappear, copied events can update, delete, stay, or become cancelled.
Prefixes and templates
Use names like Work: Client call, Personal: Busy, or keep every copied event simply named Busy.
OAuth, not passwords

FAQ
Common calendar merge questions.
Does Sync Calendars replace my calendar app?
No. It keeps your existing Google and Outlook calendars, then copies appointments into the calendar you want to use as your hub.
Can I sync Google Calendar with Outlook?
Yes. Connect both accounts, choose the Google calendar as a source, choose the Outlook calendar as the destination, and pick what the copied events should show.
Can copied events hide meeting details?
Yes. Busy-only mode creates private blockers without title, attendees, location, description, or meeting links.
Do you need my Google or Microsoft password?
No. Users connect through Google and Microsoft OAuth. Sync Calendars stores access tokens, not account passwords.
