Cross the International Date Line: Private Dateline Ceremony & Time-Travel Ritual

Mark the exact moment your ship crosses the 180th meridian with a private deck ceremony, personalized certificate, and champagne toast — the ultimate 'I lost a day (or gained one)' bucket-list moment on the open Pacific.

What to expect

As the ship approaches 180° longitude, Cunard's officers host a bridge presentation explaining the science and history of the International Date Line. Guests gather on deck for the precise crossing moment, marked by the ship's horn and a champagne toast. A beautifully printed, personalized certificate — a collector's keepsake — is presented in true White Star fashion. The crossing happens at sea, meaning your full attention is on the spectacle of open Pacific and the surreal sensation of 'time travel.'

Good to know

This is a cruise-by / at-sea event — no port tender required. Check the Daily Programme the night before for the exact crossing time, as it varies by itinerary. Cunard transpacific routes cross the IDL on select World Voyage and Transpacific sailings; confirm your voyage's crossing day when booking.
