About

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).
