Auto-Copy Events Between Google Calendars

automatically copy events from one google calendar to another

Managing multiple Google Calendars becomes a daily headache when you need to automatically copy events from one Google Calendar to another. Whether you're a freelancer juggling client accounts, a consultant managing personal and professional schedules, or someone who simply needs events to appear across different calendars, the manual copy-paste routine gets old fast.

The good news? You have several options to automate this process, from native Google features to third-party tools that handle the heavy lifting. Let's walk through four proven methods that actually work, starting with the simplest solutions.

Method 1: Use CalSync for Instant Multi-Calendar Management

If you're managing multiple Google Workspace accounts (common for freelancers and consultants), CalSync offers the most straightforward solution. Instead of copying events between calendars, CalSync creates a unified view that displays all your calendars in one place.

Here's how it works: Connect your various Google accounts to CalSync, and it automatically syncs all your calendars into a single, color-coded view. You see everything at once without duplicate entries or manual copying.

This approach eliminates the need to copy events entirely. Your client meetings, personal appointments, and project deadlines all appear together, properly organized and automatically updated. Try CalSync for $2.99/month with a free trial to see if this unified approach works better than copying events around.

Method 2: Import and Subscribe to Calendars Within Google Calendar

Google Calendar's built-in import and subscription features can automatically pull events from other calendars. This method works well when you have access to the source calendar's sharing settings.

Setting Up Calendar Subscriptions

First, get the calendar's sharing URL from the source calendar:

  1. Open Google Calendar and navigate to the source calendar
  2. Click the three dots next to the calendar name
  3. Select "Settings and sharing"
  4. Scroll to "Access permissions" and make the calendar public or share with specific people
  5. Copy the calendar ID from the "Integrate calendar" section

Then import it into your target calendar:

  1. In your destination Google Calendar, click the "+" next to "Other calendars"
  2. Select "From URL"
  3. Paste the calendar URL
  4. The events will automatically sync going forward

Limitations to Consider

This method has some drawbacks. You can't edit imported events directly—they remain read-only in your target calendar. Also, you need proper sharing permissions for each source calendar, which isn't always feasible with client accounts.

The imported calendar appears as a separate layer, so you'll see both your original events and the imported ones, which can create visual clutter.

Method 3: Google Calendar Sync Using IFTTT (If This Then That)

IFTTT provides a middle-ground automation solution that can copy specific events based on triggers you define. This works particularly well when you want selective copying rather than full calendar duplication.

Creating an IFTTT Applet

Here's the step-by-step process:

  1. Create an IFTTT account and connect your Google Calendar
  2. Choose "Create" to build a new applet
  3. Select Google Calendar as your trigger service
  4. Choose a trigger like "New event created" or "Event from search"
  5. Configure the trigger conditions (specific keywords, calendar, etc.)
  6. Select Google Calendar as your action service
  7. Choose "Create a detailed event" as the action
  8. Map the event details from source to destination
  9. Test and activate the applet

IFTTT Trigger Examples

Some practical trigger combinations:

  • Copy events containing "Client Meeting" to your professional calendar
  • Move events tagged with specific keywords to a project calendar
  • Duplicate recurring events to a backup calendar
  • Forward events from one time zone to another with time adjustments

IFTTT's free tier includes basic functionality, but you're limited to three applets. The Pro version ($3.99/month) removes these restrictions and adds faster trigger processing.

Method 4: Advanced Automation with Google Apps Script

For tech-savvy users who need precise control over event copying, Google Apps Script provides unlimited customization. This method requires basic coding knowledge but offers the most flexibility.

Basic Script Structure

Here's a simplified script that copies events between calendars:

function copyEvents() {
var sourceCalendar = CalendarApp.getCalendarById('source-calendar-id');
var targetCalendar = CalendarApp.getCalendarById('target-calendar-id');

var events = sourceCalendar.getEvents(new Date(), new Date(Date.now() + 7*24*60*60*1000));

events.forEach(function(event) {
if (!eventExists(targetCalendar, event)) {
targetCalendar.createEvent(
event.getTitle(),
event.getStartTime(),
event.getEndTime(),
{
description: event.getDescription(),
location: event.getLocation()
}
);
}
});
}

Setting Up Automated Execution

To run this script automatically:

  1. Open Google Apps Script (script.google.com)
  2. Create a new project and paste your code
  3. Set up time-based triggers in the project settings
  4. Choose how frequently the script should run (hourly, daily, etc.)
  5. Authorize the necessary permissions for calendar access

This method requires ongoing maintenance and troubleshooting, but it can handle complex copying rules that other methods can't match.

Choosing the Right Method for Your Needs

Your best option depends on your technical comfort level and specific requirements.

For most freelancers and small business owners managing multiple Google Workspace accounts, CalSync provides the cleanest solution. You avoid the complexity of copying events while getting a comprehensive view of all your commitments. Check out CalSync to see how it handles your multi-calendar chaos.

If you need to merge calendars permanently or work with calendars you fully control, the import method works well. For selective copying based on specific rules, IFTTT offers good automation without technical complexity.

Google Apps Script makes sense when you have unique requirements that pre-built tools can't handle, but be prepared to invest time in setup and maintenance.

Making Your Choice and Getting Started

The key to successfully automatically copying events from one Google Calendar to another lies in understanding your workflow first. Do you need everything synced, or just specific types of events? Are you working across multiple Google accounts, or within a single workspace?

For the majority of freelancers and solopreneurs dealing with multiple client calendars, unified viewing (rather than copying) often solves the underlying problem more elegantly. When you can see all your calendars together without the maintenance overhead of copying events, you save time and reduce scheduling conflicts.

Start with the simplest solution that meets your needs. You can always layer on additional automation as your requirements become more complex. The goal is spending less time managing calendars and more time focusing on your actual work.
