The Easiest Way to Automatically Mirror Google Calendars
Set up automatic calendar mirroring in minutes. Never manually copy events again—GCalSync mirrors your calendars automatically.
Last updated: 2025-11-15
What is Calendar Mirroring?
Calendar mirroring means creating an exact copy of events from one calendar to another. When you create, update, or delete an event in the source calendar, the same change automatically happens in the mirrored calendar.
Traditional approach: Manually copy events between calendars, remember to update both when things change, risk forgetting to sync important events.
GCalSync approach: Connect calendars once, set up automatic mirroring, and forget about it. Events sync automatically every 15-30 minutes.
Why GCalSync is the Easiest Solution
✅ Set Up in Minutes
No complex configuration, no coding, no technical knowledge required. Just connect your calendars and choose your sync direction. The entire setup takes less than 5 minutes.
✅ Fully Automatic
Once configured, GCalSync runs automatically every 30 minutes. You don't need to remember to sync, click buttons, or check anything. Your calendars stay mirrored without any effort.
✅ Smart Duplicate Prevention
GCalSync automatically prevents duplicate events. It tracks which events have been synced and won't create copies of copies. You'll never see the same event twice.
✅ Works Across Google Accounts
Mirror calendars from different Google accounts. Perfect for syncing work and personal calendars, or managing multiple client accounts.
✅ Privacy Controls
Mirror events while keeping details private. Use privacy mode to show only "Busy" on mirrored calendars without revealing event titles, descriptions, or locations.
How to Set Up Automatic Mirroring
Step 1: Connect Your Calendars
- Sign in to GCalSync
- Click "Connect Calendar"
- Authorize access to your source calendar (the one you want to mirror)
- Connect your target calendar (where events will be mirrored)
Step 2: Create the Mirror Sync
- Go to Dashboard → Syncs
- Click "Create Sync"
- Select your source calendar
- Select your target calendar
- Choose sync direction:
- One-way: Source → Target (mirrors source to target only)
- Bidirectional: Source ↔ Target (mirrors both directions)
- Click "Create Sync"
Step 3: That's It!
Your calendars are now set to mirror automatically. GCalSync will:
- Sync existing events immediately
- Continue syncing new events every 30 minutes
- Update events when they change
- Remove events when deleted from source
One-Way vs Bidirectional Mirroring
One-Way Mirroring (Source → Target)
Events flow from source to target only. Perfect when you want to:
- Mirror your work calendar to personal calendar (read-only view)
- Distribute team calendar to individual calendars
- Publish one calendar to multiple others
Bidirectional Mirroring (Source ↔ Target)
Events flow in both directions. Perfect when you want to:
- Keep work and personal calendars fully synchronized
- Mirror multiple calendars that all need to stay in sync
- Create events in either calendar and have them appear in both
Advanced Mirroring Options
Privacy Mode
Mirror events while hiding details. Enable privacy mode on your target calendar to show only "Busy" or custom placeholder text instead of event titles and descriptions.
Event Prefixes
Add prefixes to mirrored events so you know where they came from. For example, "[Work]" or "[Personal]" before event titles.
Custom Colors
Assign different colors to mirrored events to visually distinguish them from native events.
Mirror Multiple Calendars
Use sync groups to mirror multiple calendars at once. Create a sync group with 3+ calendars and GCalSync automatically creates bidirectional mirrors between all pairs.
Why Not Use Google Calendar's Native Features?
Google Calendar has some built-in sharing features, but they don't actually mirror events:
- Calendar sharing: Only shows events, doesn't copy them
- Calendar visibility: Just makes calendars visible, not synced
- Import/Export: Manual, one-time process, not automatic
- Multiple accounts: Requires constant switching, no automatic sync
GCalSync actually mirrors events—creating real events in target calendars that you can edit, delete, and interact with just like native events.
Common Use Cases
Work → Personal Mirror
Mirror your work calendar to your personal calendar so you can see work commitments when planning personal time. Use one-way sync with privacy mode to hide meeting details.
Personal → Work Mirror
Mirror personal appointments to work calendar so coworkers see you're busy without knowing why. Perfect for doctor appointments, personal errands, etc.
Bidirectional Mirror
Keep work and personal calendars fully mirrored. Create an event in either calendar and it automatically appears in the other. Never double-book again.
Team Calendar Mirroring
Mirror a central team calendar to individual team member calendars. Everyone sees team events on their own calendar automatically.
Common Questions
How often does mirroring happen?
GCalSync automatically mirrors calendars every 30 minutes. You can also trigger manual syncs anytime with the "Sync Now" button.
Will mirrored events look different?
Mirrored events are real Google Calendar events. They look and behave exactly like native events. You can optionally add prefixes or colors to identify them, but they're fully functional calendar events.
What if I delete a mirrored event?
If you delete a mirrored event from the target calendar, it will be recreated on the next sync (since it still exists in the source). To permanently remove it, delete it from the source calendar or pause the sync.
Can I mirror calendars from different Google accounts?
Yes! GCalSync supports calendars from multiple Google accounts. Connect calendars from different accounts and mirror between them seamlessly.
