About this tool
A timezone converter answers one practical question: if an event is at a given local time in one place, what clock time is that for someone somewhere else. You pick a source timezone and datetime, choose a destination timezone, and get the equivalent local time with daylight-saving rules applied for that date. That removes the usual meeting mistakes - inviting someone an hour early after a DST change, or reading a flight arrival in the wrong city. It is for exact conversion of one moment, not a live world clock of many cities at once. Once you have the mapped time, paste it into calendar invites, travel plans or support handoffs so every side shares the same instant.
