Officely offers an integration with your Google Calendar so that all your office days are synced in your calendar. This allows your colleagues to easily see which days you are in the office.
Officely will mark your office days by adding an all-day event in your calendar with the name of your office. This only shows up in the section at the top, it will not monopolise other events.
How to Set Up
From Officely Home go to Settings > Your Preferences > Scroll down to Integrations > Click 'Connect' next to the Google Calendar box. Google will then take you through an authorisation flow.
