Converts one moment across several time zones, daylight saving time included. WHEN TO USE: "what time is it in…", scheduling a meeting across cities, checking whether a time falls at night or on another day somewhere. HOW IT WORKS: - zones: IANA time zone names in Area/City form — America/Sao_Paulo, Europe/Lisbon, Asia/Tokyo, UTC. Not city names alone, abbreviations (EST, BRT) or offsets (GMT-3). The FIRST zone is the reference for date and hour. 1 to 12 zones. - date (YYYY-MM-DD) and hour (0–23) are read in the first zone. Without them: the current moment. Only hour: that hour today in the first zone. Only date: that day at the current hour. - format: 24h (14:00) or 12h (2:00 PM). RETURNS: the moment in UTC and, for each zone, its local date, weekday, time, UTC offset and dayShift (+1 = next day, -1 = previous day, relative to the first zone). link: this tool's web page with the same comparison. ERRORS name the unknown zone or the invalid date; fix it and call again.
