About Timezones Dictionary API
Timezones Dictionary API is a hosted API from ApyHub that returns a live list of time zones with their current UTC offsets. Each entry in the response includes an ISO 3166-1 alpha-2 country code, an IANA time zone name, the current UTC offset, and one or more matching abbreviations. The offset values are computed live, reflecting daylight saving time changes without requiring the consumer to maintain a separate table.
The API exposes a single GET endpoint that returns a JSON object containing a data array of these timezone records. It is suited for use cases such as scheduling, calendar logic, region-aware defaults, booking flows, attendance tools, delivery planning, and UI pickers that map countries to time zones.
