Time Zone Tooltip

Time Zone Tooltip turns every time you read on the web into your local time. Hover over 14:30 UTC, 9am PST, 2026-05-23T14:30:00Z, 09:30–11:00 26.05.2026, or "tomorrow at 9 a.m." and a small tooltip shows the converted local time, with the date when relevant — plus a world map highlighting both time zones. WHAT IT RECOGNISES - Explicit time zones — 14:30 UTC, 9pm PST, 09:30 CET, JST, IST, CST, and 40+ more abbreviations - UTC offsets — 14:30 UTC+2, 14:30+0200, 09:00 GMT-5 - ISO 8601 timestamps — single times and ranges, with milliseconds, with offsets, with Z - Time ranges — 9–17 UTC, 9am–5pm PST, 7:30 a.m. to 8:45 a.m. - Bare times with an assumed source zone — 14:30 and 7 a.m. to 9 a.m. get converted when a source zone is configured or auto-detected from the page's language or top-level domain - Date context — tomorrow at 14:30 UTC, on May 30 at 9pm PST, am 15. Juni 2027, 26.05.2026, weekday hints like next Monday SMART CONTEXT AWARENESS - Auto-detects the page's likely source zone from <html lang>, og:locale, or the TLD - Disambiguates ambiguous abbreviations from context — IST near "Mumbai" maps to India, near "Dublin" to Ireland, near "Tel Aviv" to Israel - Reads modern single-page apps, including content inside closed shadow DOM - Handles daylight-saving transitions automatically via the browser's built-in Intl API PER-SITE CONTROL - Turn the extension off on individual domains - Set a source zone per domain when auto-detection guesses wrong - Set a global fallback source zone for sites without language or TLD hints - All settings stored locally in your browser, never synced or sent anywhere PRIVACY - 100% offline. No servers contacted. No analytics. No remote scripts. - Permissions: storage (your settings) and activeTab (popup reads the current URL).
