Calendar integration (event app)

Business attendees run their lives from their work calendar, not from your app. A meeting that exists only inside the event app is an appointment with no reminder in the system the attendee actually checks — which is a measurable driver of no-shows for one-to-one meetings that both parties genuinely wanted. Calendar integration closes that gap: sessions and meetings sync out, reminders fire from the attendee's own device, and a meeting booked three weeks before the show survives contact with a busy diary. In practice, the details separate good implementations from token ones. One-way .ics file downloads are the weakest form — they create a static entry that goes stale the moment a session moves. Live sync via calendar subscription or OAuth connection keeps entries current through reschedules, which matters at trade events where agendas shift late. Timezone handling deserves explicit testing for events with international audiences: a 09:00 session displaying as 03:00 in a synced calendar is a support-desk classic. The common mistake is burying the sync option three menus deep — put "add to my calendar" at the moment of booking, when motivation is highest. One honest nuance: corporate IT policies block OAuth calendar connections at some companies, so always keep the humble .ics fallback available even if it's the worse experience.
