[{"body":"Time Zone World publishes practical, route-by-route guides to the time-zone side of long-distance travel: how long a flight really takes, how many hours ahead or behind the destination runs, which direction the jet lag hits hardest, the airlines that fly the route, and the best time of year to go.\nMost \u0026quot;time zone\u0026quot; pages stop at a ticking clock. Time Zone World works the rest out for the reader — distance and flight time from great-circle calculations, the current offset between cities, the effective body-clock shift once the International Date Line is accounted for, and a business-hours overlap window for scheduling calls across the gap.\nPublisher Time Zone World is published by Harman Research, an independent web publisher that operates a portfolio of reference and niche-interest sites. More about the publisher is available at harmanresearch.com.\nHow the guides are built Route facts are computed at build time from open aviation and time-zone data — airport coordinates, IANA time-zone offsets, and published route schedules — rather than left to load in your browser. Figures such as flight time are great-circle estimates for typical jet cruise speeds and will differ from a specific airline's scheduled block time, which varies with routing, winds, and aircraft. Where a route has no scheduled nonstop service, that is stated rather than implied.\nFor questions or corrections, please use the contact page.\n","link":"https://www.timezoneworld.info/about/","section":"","tags":null,"title":"About Time Zone World"},{"body":"Have a question, a route you'd like added, or a correction?

Most \u0026quot;time zone\u0026quot; pages answer none of that — they show a ticking clock and leave the rest to you.\nEach route page here works it out at a glance.
