My night ends after midnight, or days later

An event's end is a date and a time, not just a time. A night from 9 PM to 3 AM ends on the next day, and the end has to say so.

On the web, set Starts and Ends. Beside Ends is a day stepper that reads same day or +1 day, +2 days and so on. Press the up arrow for a festival or a weekend run, and the down arrow to bring it back. The line underneath says the day it ends, such as "Ends Monday 9 Nov." Anything longer than two days asks if that is deliberate, but still saves.

When you create an event, an end time at or before the start time is taken to be the next day until you touch the stepper, so an ordinary late night needs nothing more. In Edit event the stepper stays where you set it, and an end before the start is refused with "That ends before it starts. Add a day, or move the end time later."

In the app, End Time has its own Date and Time. For a night past midnight, set the end Date to the next day as well as the time. An end at or before the start is refused with "The end time has to be after the start time."

Ticket sales close when the event ends, so a wrong end date can close sales early. See Sales close when the event ends.
