Scheduling across time zones goes wrong in a predictable way: someone does the arithmetic from memory, forgets that one country has already moved its clocks and the other has not, and a meeting lands an hour out. This free time zone converter removes the arithmetic entirely.\n\nAdd the cities that matter and see them side by side, either live or at a specific future moment. When you enter a time you also say which zone it is in, and every other city is converted from it — the actual question behind most scheduling, which is 'if we meet at 3pm my time, what time is that for everyone else?'\n\nEach city carries a plain indicator: work hours, off hours, or asleep. It is a rough signal rather than a claim about anyone's calendar, but it makes an unreasonable slot obvious at a glance instead of after someone declines. Offsets are shown exactly, including the genuinely half-hour and quarter-hour zones like India at UTC+05:30 and Nepal at UTC+05:45.\n\nAll of it comes from your browser's own IANA time zone database through the Intl API, so daylight saving is applied correctly for the date you pick and there are no network requests. Pair it with the Date Difference Calculator for spans of days, or the Unix Timestamp Converter when you are debugging times in code.
