3. How to Access Google Calendar Offline
If you're traveling and don't have access to an Internet connection, you can still access your calendar. To enable Offline, you must download the Google Chrome browser. Click the gear icon and choose "Offline" from the drop-down menu. You'll be prompted to install the Google Calendar Web application from the Chrome Web Store.
Once the installation is complete, a new Chrome tab will open and the Google Calendar Web app icon will appear. Click the icon to go to Google Calendar. Next to "Offline," you should see a green icon with a checkmark. This indicates that your calendar is synched and ready to use offline. If your calendar is still syncing, you'll see a green spinning icon.
