Arrival and lodging dates
This compares the instant you leave with the local start and end written on a lodging reservation. Crossing the date line can put the arrival on a different calendar date from the departure.
Enter the departure IANA time zone, the local departure date and time, the travel time in minutes, the lodging IANA time zone, and the reservation’s local check-in and check-out. There is no field for a hand-typed UTC offset.
Leave Tokyo (Asia/Tokyo) at 2026-01-15 08:00, travel 600 minutes, and lodge in Honolulu (Pacific/Honolulu). Arrival is local 2026-01-14 23:00 (UTC-10:00). With check-in 2026-01-15 15:00 and check-out 2026-01-16 11:00, you wait 960 minutes until the reservation starts. 2160 minutes remain until it ends, and the stay is 1 night on the lodging calendar.
The same arrival with check-in 2026-01-14 15:00 and check-out 2026-01-15 11:00 falls inside the reservation. 480 minutes have passed since the start, 720 minutes remain until the end, and the stay is 1 night on the lodging calendar.
The ride from the airport, the reception hours, and whether the booking is actually valid cannot be judged here.
