⚠ What this tool does and doesn't do
  • DST is handled automatically by your browser's built-in timezone engine (the Intl API). Conversions are correct for past and future dates for all IANA timezone entries listed.
  • Business hours overlap is hardcoded as 9 AM–5 PM in both zones. We cannot know your actual working hours. Use the 24-hour reference table below for a custom read.
  • The timezone list is curated — it covers ~120 major cities. Smaller or less-common IANA zones (e.g. America/Indiana/Vincennes) are not listed. If your zone is missing, pick the nearest major city in the same offset.
  • No map is shown. A reliable interactive world map with accurate day/night rendering requires a mapping library (e.g. Leaflet + a tile server) which we do not load. We chose accuracy over decoration.
  • Share Link copies a URL to your clipboard. It requires the page to be served over HTTPS for clipboard access in some browsers.
