Syncing your Google Calendar with other apps and devices keeps your schedule organized and accessible. This guide walks you through how to import Google Calendar data securely and efficiently across platforms.
Below is a quick reference for the most common import scenarios, including what you need, where to act, and what to expect after the import finishes.
| Method | Where to Start | What You Need | Time to Complete |
|---|---|---|---|
| Import ICS/CSV file | Google Calendar settings on the web | ICS or CSV file from another calendar | 5–10 minutes |
| Sync via Google Takeout | Google Takeout account | Google account, storage space | 15–45 minutes |

| Mobile device sync | Device settings or calendar app | Google account on device | 5–15 minutes |
Preparing to Import Events
Before you import, organize the events you want to move into a single file. Exporting from your current calendar usually gives you an ICS or CSV file that Google Calendar can read.
Check that the file includes clear date times and time zones so events appear correctly. Clean up duplicates and adjust formatting to reduce errors during the import process.
Once the file is ready, sign in to Google Calendar on the web so you can access the import tools from the left side navigation.
Importing an ICS or CSV File
Importing an ICS or CSV file is the fastest way to bring events into Google Calendar from another service.
Exporting from your current calendar
In your original calendar, look for an export or download option that saves events as an ICS or CSV file.
Uploading the file to Google Calendar
In Google Calendar, click Settings, choose Import & export, select the file, choose the destination calendar, and click Import.
Using Google Takeout for Bulk Data
Google Takeout lets you download and re-import your Google Calendar data as part of a larger archive or as a separate file.
Creating a Takeout export with calendar data
Go to the Google Takeout page, deselect unnecessary data, keep Calendar selected, choose file type and size, and then create the export.
Importing the Takeout file back into Google Calendar
Download the archive, extract the ICS file for your calendar, and use the import option in Google Calendar to upload it to the target calendar.
Syncing Third-Party Apps with Google Calendar
Many productivity and scheduling apps support two-way sync with Google Calendar, keeping events consistent across tools.
Connecting an app to your Google Calendar
In the app, locate calendar integration, authorize access to your Google account, and select the calendar you want to sync.
Managing sync direction and filters
Choose whether events sync in one direction or both, and set filters to include only specific calendars or event types.

FAQ
Reader questions
Will importing events change or delete existing events in my calendar?
Importing events adds new events to the destination calendar and does not change or delete existing events, unless a file contains edits or conflicts that you manually apply.
How can I import Google Calendar events into Outlook or another calendar app?
Export your Google Calendar as an ICS file, then import that file into Outlook or another calendar app through its import or add calendar feature.
Can I import only events from a specific date range?
When using a file export, filter events by date in the source calendar before exporting so the file contains only the range you want to import.
What should I do if time zones shift after importing events?
Verify the time zone of the destination calendar and ensure your export file includes time zone data, then reimport with the correct settings if needed.
