Get the IANA time zone, local time, UTC offset, abbreviation and DST status for any latitude and longitude. Fast and offline, no upstream limits.
The API returns data related to time zones based on latitude and longitude, including the IANA time zone name, local time, UTC offset, abbreviation, and daylight saving time (DST) status.
Key fields in the response include "timezone" (IANA time zone), "localTime" (current local time), "utcOffset" (offset from UTC), "abbreviation" (time zone abbreviation), "isDst" (DST status), and "lat" and "lon" (coordinates).
The primary parameters are latitude ("lat") and longitude ("lon"). Optionally, you can pass a "datetime" parameter to retrieve the UTC offset for a specific moment in time.
The response is structured as a JSON object containing key-value pairs. Each field provides specific information, such as coordinates, time zone details, and local time, making it easy to parse and utilize.
Typical use cases include scheduling applications, travel planning, event coordination across time zones, and any scenario requiring accurate local time and time zone information based on geographic coordinates.
Data accuracy is maintained through reliable sources of time zone information, regular updates, and adherence to IANA time zone standards, ensuring that the API provides current and precise time zone data.
Users can utilize the returned data to display local times, calculate time differences, manage scheduling across regions, and determine whether DST is in effect, enhancing applications that depend on accurate time zone information.
The API covers all global regions represented by IANA time zones, including major cities and remote areas, ensuring comprehensive time zone data for any valid latitude and longitude input.
