The time or date looks wrong

• Your event has its own Time zone. A new event starts with the time zone of the device you create it on, and you can change it while creating the event or later.
• Your invitation, the emails to your guests and the app show the date and time in that time zone.
• When a guest's phone or computer is in another time zone, the invitation names the time zone after the time. Emails to guests name it too.

Changing the time zone keeps the clock time you entered: 15:00 stays 15:00, now in the new time zone. If your venue seems to be in another time zone, the app suggests the venue's time under the place.

The invitation email, and the reply confirmation of guests who are coming, include a calendar file. Calendar apps show the event in the time zone of the guest's own device, so a guest in another country sees their local time. It is the same moment, so this is correct.

When you change the date, time or time zone, the update email carries a new calendar file. If a guest's calendar still shows the old time, they can delete the old entry and add the new one.

• A date in the past cannot be chosen.
• After the event, the date can no longer be changed. If it was entered wrongly, contact support and we will correct it.
• If the phone app shows 1 July 2100, that event has no date yet and your app is an older version. Update the app, and add the date in Event settings when you know it. See events without a date.
