How to Sync Multiple Google Calendars
The Problem: Multiple Google Calendars = Multiple Headaches
You have a work Gmail, personal Gmail, maybe a family shared calendar. People only see one calendar when booking with you, leading to embarrassing conflicts.
Double Bookings
Client schedules during your dentist appointment because they can't see your personal calendar.
App Juggling
Switching between multiple Google Calendar apps just to see your full schedule.
Privacy Dilemma
Share your work calendar = colleagues see personal events. Don't share = double bookings.

Connect unlimited Google calendars. Sync happens automatically in real-time. Privacy-first design keeps personal details private while preventing double bookings.
Connect Google Accounts
Sign in to each Google account you want to sync. Work, personal, family - as many as you need.
Choose Sync Direction
For each calendar: Should it share busy times? Should it receive busy times? Usually "yes" to both.
Enjoy Perfect Sync
That's it! MergeDay automatically syncs busy times between calendars every 30 seconds.

👔 Professional Use
Work + Personal Split
You have [email protected] and [email protected]. You want colleagues to know when you're busy (for personal appointments) without seeing what those appointments are.
Freelancer/Consultant
Working with multiple clients, each with shared Google calendars. Your personal time needs to block across all client calendars automatically.
Multiple Organizations
Board member, volunteer coordinator, part-time contractor. Each role has its own Google account that needs to respect your other commitments.
👨👩👧👦 Personal Use
Family Coordination
Parents with individual Google calendars plus a shared family calendar. Kids' activities should block everyone's availability automatically.
Couple Sharing
Both partners want to share availability without sharing every personal detail. Perfect privacy balance.
Student Life
School account, work account, personal account. Study sessions should block across all calendars so friends know when you're unavailable.
