Swatch once tried to kill time zones with .beats. But could UTC be the serious replacement the world actually needs? -
Best overlap: 5:30 PM to 6:30 PM in Mumbai is 8:00 AM to 9:00 AM in New York.
Target 5:30 PM to 6:30 PM in Mumbai, which lands at 8:00 AM to 9:00 AM for the New York side. Overlap is at a premium — roughly 1 hour — so claim 5:30 PM in Mumbai (8:00 AM in New York) for recurring calls and keep them on time. Seasonal note: New York uses daylight saving and Mumbai doesn't, so double-check the times in your own months — they can move by an hour.

8 AM Tokyo is 4 PM in Los Angeles the day before. West Coast afternoon windows, the East Coast dead zone, and why the Philippines slot is an hour off. -
London to New York is five hours apart, except for the five weeks a year when it isn't. Exact overlap windows for every US zone, the 2026 DST mismatch dates, and where to put the recurring sync. -
