How to Set Up Calendar Synchronization: Step by Step

Complete guide to setting up automatic synchronization between your calendars.

Managing multiple calendars doesn't have to be complicated. This guide will show you how to set up automatic synchronization in just a few minutes.

Why Synchronize Calendars?

If you use multiple calendars (work, personal, family), you probably know these problems:

  • ❌ Double booking important meetings
  • ❌ Forgotten events
  • ❌ Conflicting times between calendars
  • ❌ Manual copying of events

The solution is automatic synchronization, which ensures that when time is occupied in one calendar, it is automatically blocked in all others.

Setup Process (5 Steps)

Step 1: Connect Your Calendars

First, connect all calendars you want to synchronize:

  1. Log in to SyncMyDay
  2. Click "Connect Calendar"
  3. Select provider (Google, Microsoft, Apple...)
  4. Authorize access
  5. Repeat for all your calendars

Step 2: Create Synchronization Rule

A synchronization rule defines how events should be transferred between calendars:

  • Source calendar: where events come from
  • Target calendar: where events are copied as "Busy"
  • Filters: optionally you can synchronize only certain types of events

📌 Example:

Work calendar (Google) → Personal calendar (Apple iCloud)
When you add a meeting to your work Google calendar, a blocking event "Busy" is automatically created in your personal iCloud calendar.

Step 3: Set Filtering (Optional)

You can synchronize:

  • ✅ All events
  • ✅ Only events where you are marked as "Busy"
  • ✅ Only all-day events
  • ✅ Events containing certain keywords

Step 4: Activate Rule

With one click, activate synchronization. The system will immediately start monitoring changes and synchronizing events in real-time.

Step 5: Test Functionality

Create a test event in the source calendar and verify that it appears in the target calendar within a few seconds.

Frequently Asked Questions

How quickly do events synchronize?

Synchronization occurs almost instantly thanks to webhooks. A new event is transferred to the target calendar within 1-5 seconds.

Do people see the content of my events?

No! Only a blocking event with a generic name "Busy" is created in the target calendar. Details of your event remain private.

Can I synchronize multiple calendars at once?

Yes! You can create unlimited synchronization rules and thus synchronize any combination of calendars.

What if I delete an event?

If you remove an event from the source calendar, the corresponding blocking event in the target calendar is automatically deleted as well.
