This is exactly what AddEvent's subscription calendars are designed for. When someone subscribes to your AddEvent calendar, their calendar app creates a live connection to your calendar feed. Any event you add, edit, or remove syncs to all subscribers automatically.

How updates reach subscribers

When you make a change in AddEvent - reschedule an event, add a new session, fix a typo in the description, cancel an event - the change is reflected in your calendar feed immediately. Subscribers' calendar apps poll that feed on their regular schedule (typically every few hours for Apple and Outlook; every 12-24 hours for Google Calendar) and apply any changes.

What updates automatically

• New events you add appear in all subscribers' calendars
• Event title, date, time, location, and description changes sync across
• Cancelled events are removed from subscribers' calendars

Limitations to know

• You cannot push an instant update to all subscribers - sync timing depends on each subscriber's calendar app
• Google Calendar is the slowest (12-24 hours); for urgent changes, a manual refresh is available
• Subscribers can unsubscribe from within their own calendar app at any time

The practical workflow

1. Create a subscription calendar in AddEvent
2. Share the Follow Calendar button or link with your audience
3. They subscribe once - all current and future events are delivered automatically
4. You manage your calendar in AddEvent; subscribers never need to take action again
