Which languages is the request page available in?
The request page is available in English, German, French, Spanish, Portuguese, Italian, Dutch, Polish, Swedish, Danish, Norwegian, Finnish, Turkish, Japanese and Korean.
You pick the language when you create your event. Because the language forms part of the event's web address, the QR & Share tab also lets you switch it for the link and QR code you're about to hand out — choose a language there and the link you copy carries it. Guests don't select anything themselves: whatever is in the link is what they see, and the event date is formatted to suit that language too.
Choose the language your guests speak rather than your own. A British DJ working a wedding in Spain will get noticeably more requests with the page set to Spanish than left in English.
Each event keeps its own language, so a French wedding and a Dutch corporate night can run side by side without affecting each other.
