Don't Double Book Me

Don't Double Book Me automatically synchronizes events between two Google Calendars to prevent scheduling conflicts. The web-based application connects any two of the user's Google Calendars and syncs events in real-time where the availability is marked as "Busy" based on user preferences for visibility, working hours, and time rounding. Key features include setting specific working hours to separate personal and professional calendars, rounding event start and end times to the nearest 15/30 minutes for tidy scheduling, and syncing pending invitations to avoid double bookings.
