How to use this calculator
Enter each departure and arrival with its local date, time and IANA zone. Add accommodation check-in/out intervals in their local zones and choose how to resolve repeated clock times.
Legs sort by actual departure instant. Arrival must follow departure within fourteen elapsed days. Accommodation gaps measure elapsed time outside supplied stays; overlapping legs, stays and transport/accommodation intervals are listed for review.
A worked example
Leaving Los Angeles at 10:00 on November 2, 2026 and arriving in Tokyo at 15:00 November 3 takes 12 elapsed hours. A hotel from November 3 at 16:00 to November 5 at 08:00 leaves two hours outside accommodation before a 09:00 departure.
Does a gap mean I need another hotel booking?
Not necessarily. Airport transfers, sightseeing and check-in times naturally leave gaps. Use the breakdown to inspect your itinerary; no live airline or hotel records are loaded.
Which calendar and years are supported?
Use Gregorian dates from 1900 through 2100, with results in that range. Most daily plans allow up to 366 dates; service-budget searches allow 731. Timed intervals have exclusive ends and use browser IANA time-zone rules; nonexistent local times are rejected and repeated times require your choice. Working calendars and policy terms are entered by you. The holiday comparison uses TimeCubby's published country/region coverage. Copy, CSV and print include assumptions; calendar exports appear when dated events exist.
