Google Calendar allows exporting and importing events, but only for one-time transfers. Zapier can be used to set up automatic workflows that copy new appointments from one calendar to another, allowing for continuous updates. Users can create their own Zaps without coding knowledge or use pre-built templates to get started. To set up a Zap, users need to connect their Google Calendar account, select the correct calendar, and configure the trigger and action steps. The action step includes setting event details such as summary, description, location, start and end times, and repeat settings. Alternatively, users can manually export and import events from one Google Calendar to another using the built-in export and import features in Google Calendar.
