No copied calendar, just a way to check for yourself

Find the organiser's own page

A real event always has a page or a social account belonging to the body running it. A third-party aggregator is only useful for finding the organiser's name, after which you should go back to the original page.

Check date, time and time zone

This area sits in the US Eastern time zone. The time on a ticket and the time on an event page are sometimes an hour apart because one of them has not switched for the season. Take the organiser's figure.

Look for the cancellations or rescheduling section

Outdoor events on the beach are often moved because of weather. An organiser's page will usually have a separate section headed updates or notices. Read that one, not just the top of the page.

Check access and parking

Beach parking runs on seasonal permits and fills quickly on festival weekends. Check the parking limits first, because that is the most common reason people give up on attending.

Check the weather situation

Hurricane season runs long over the Atlantic. Before travelling, read the official forecast and warnings, and check the water too — a strong rip current is the most common reason lifeguards have to intervene.
