Timezones List API

What it does

Time Zone List returns the full set of IANA timezone names, with an optional keyword filter for narrowing the results. Send a search query string and get back a timezones array of matching timezone identifiers.

Use it when you need a dependable source of timezone names for scheduling, user profile settings, region pickers, or validation in forms and admin tools. Because the response is just the timezone list, it fits cleanly into lookup flows where you already know how to present or cache reference data.

Time Zone List is useful anywhere you need to avoid hardcoding timezone values or keeping a local copy of the IANA set up to date. Filter by keyword to find the subset you need, or request the full list when populating dropdowns and syncing reference tables.
