# GOOGLESUPER_FIND_FREE_SLOTS

Finds both free and busy time slots in Google Calendars for specified calendars within a defined time range (defaults to the current day UTC if time_min/time_max are omitted). Returns busy intervals enriched with event details and calculates free slots by finding gaps between busy periods; time_min must precede time_max if both are provided. This action retrieves free and busy time slots for the specified calendars over a given time period. It analyzes the busy intervals from the calendars and provides calculated free slots based on the gaps in the busy periods.
