Usually, the exact timing is only available a few days before the event. At that time, the schedule is automatically updated on the website and made available to the Customer Experience Center.
You can find the timetable on the event page itself. Go to the Proximus Pop-Up Arena website and search for your event. Open the page and scroll down until you see 'Time schedule'.
Are there multiple shows for the event? Then you need to mark the date before the timetable pops up.
