All endpoints return JSON with permissive CORS. Data is static and CDN-cached — fast and reliable.

GET /api/cities.json

All 500+ cities with their time zones and coordinates.

fetch("https://timedatelive.com/api/cities.json")
  .then(r => r.json())
  .then(data => console.log(data.count, data.cities[0]));

// Response:
{
  "count": 500,
  "cities": [
    {
      "slug": "lisbon",
      "name": "Lisbon",
      "country": "Portugal",
      "timezone": "Europe/Lisbon",
      "lat": 38.72,
      "lon": -9.14,
      "flag": "🇵🇹"
    }
    // ...
  ]
}

GET /api/timezones.json

All distinct IANA time zones covered.

fetch("https://timedatelive.com/api/timezones.json")
  .then(r => r.json());

// { "count": 119, "timezones": ["Africa/Cairo", "America/New_York", ...] }

Getting the live time

Time zones are IANA identifiers, so you can compute live local time entirely in the browser — no server needed:

const tz = "Asia/Tokyo"; // from /api/cities.json
const now = new Intl.DateTimeFormat("en-GB", {
  timeZone: tz, hour: "2-digit", minute: "2-digit", second: "2-digit"
}).format(new Date());
// "14:32:07"
