Convert any moment between two zones and read it across 36 world cities in one table — meeting planning, on-call handoffs, flight sanity checks. DST transitions are handled by the browser’s own IANA tz database, so the same converter is correct in every country and every hemisphere.
The world-clock table doubles as the "is that hour civilized there" check: the weekday travels with the date across the midnight line.
Frequently asked questions
Why does the difference say +12.5 h?
True half-hour offsets exist — India (+5:30), Nepal (+5:45), parts of Australia. The difference is computed from the actual zones, not rounded to hours.
Does it handle DST switching days?
Yes — the instant is computed through the zone rules, so a 14:30 in London on the switch day lands correctly in New York even though that day has 23 or 25 hours there.
中文说明
在任意两个时区间转换一个时刻，并在一张表里读出全球 36 个城市的时间——排会议、交接班、核对航班都合适。夏令时切换由浏览器内置的 IANA 时区数据库处理，任何国家、任何半球都正确。
世界时钟表格还能顺手回答"那个点当地方不方便"：星期几会跟着日期一起跨过午夜线。
常见问题
为什么时差显示 +12.5 小时？
真实存在半小时偏移——印度（+5:30）、尼泊尔（+5:45）、澳大利亚部分地区。时差按真实时区算，不取整。
夏令时切换当天准吗？
准——时刻是按时区规则算出的，伦敦切换日的 14:30 换算到纽约依然正确，哪怕纽约那天只有 23 或 25 小时。
