openapi: 3.0.7 info: title: 'IPGeolocation.io: Date, Time & Timezone API' version: "3.0" description: | Retrieve current date, time, and timezone information for a specific location or identifier. The Timezone API returns detailed timezone information including the timezone name, UTC offset, daylight saving time (DST) status, current local time, formatted timestamps, and upcoming DST transition details. Timezone information can be retrieved using multiple lookup inputs: - Timezone name (IANA identifier) - Location address - Geographic coordinates (latitude and longitude) - IPv4 or IPv6 address - IATA airport code - ICAO airport code - UN/LOCODE city identifier Depending on the lookup method used, additional contextual information may be returned: - Geolocation details for IP address or location queries - Airport information for IATA or ICAO code queries - City details for UN/LOCODE queries Two endpoints are available: - **Timezone lookup** (`GET /v3/timezone`) returns timezone and current time information for a location, IP address, coordinates, timezone name, airport code, or UN/LOCODE. - **Time conversion** (`GET /v3/timezone/convert`) converts a given time between two timezones, locations, coordinates, airports, or UN/LOCODE identifiers. ## Authentication Two authentication methods are supported: ### API Key Pass your API key as the `apiKey` query parameter on every request. You can find your key in the [IPGeolocation dashboard](https://app.ipgeolocation.io/). Store it in server-side environment variables. Avoid exposing it in client-side JavaScript. ### Request Origin (CORS) Available on paid plans only. Whitelist your domain in the dashboard under the "API Keys" section. Once configured, requests from that domain (and all its subdomains) are accepted without passing `apiKey`. Enter your root domain (e.g. `example.com`), not the full URL. Each plan has a limit on the number of extra API keys and request origins: | Plan | Extra API Keys + Request Origins | |---|---| | Starter (150K requests) | 1 | | Core (250K requests) | 1 | | Plus (500K requests) | 2 | | Pro (1M requests) | 2 | | Business (2M requests) | 3 | | Premium (5M requests) | 3 | Additional keys or origins can be added for $2.50 per month each. ## Response Formats The API supports JSON (default) and XML output. - Set the `output` query parameter to `json` or `xml`. - Alternatively, set the `Accept` header to `application/json`, `application/xml`, or `text/xml`. If neither is specified, the response is returned as JSON. XML responses use a `LinkedHashMap` root element. ## Credit Usage Credits are charged only for successful **HTTP 200** responses. The exact number of credits consumed by a request is returned in the `X-Credits-Charged` response header. - A **timezone lookup** (`GET /v3/timezone`) consumes **1 credit** per request. - A **time conversion request** (`GET /v3/timezone/convert`) consumes **1 credit** per request. ## Lookup Parameter Priority If multiple lookup parameters are provided in a request, the API resolves the timezone information using the following priority order: 1. `tz` (timezone name) 2. Geographic coordinates (`lat`, `long`) 3. `location` 4. `ip` 5. `iata_code` 6. `icao_code` 7. `lo_code` ## Parameter Name Casing Query parameter names are case-sensitive. Use exact names such as `apiKey`, `tz`, `location`, `lat`, `long`, `ip`, `iata_code`, `icao_code`, `lo_code`, `lang`, and `output`. ## Timezone Data Availability Basic timezone information is also included in the IP Geolocation API (`/v3/ipgeo`) for both Free and Paid subscriptions. Extended timezone metadata such as formatted timestamps, calendar fields, and additional date/time formats are available through the dedicated `/v3/timezone` endpoint. Both `/v3/ipgeo` and `/v3/timezone` endpoints are available on **Free and Paid plans**. The difference between them lies in the **level of timezone data returned**, not plan availability. | Field | /v3/ipgeo | /v3/timezone | |---|---|---| | time_zone.name | ✓ | ✓ | | time_zone.offset | ✓ | ✓ | | time_zone.offset_with_dst | ✓ | ✓ | | time_zone.current_time | ✓ | ✓ | | time_zone.current_time_unix | ✓ | ✓ | | time_zone.current_tz_abbreviation | ✓ | ✓ | | time_zone.current_tz_full_name | ✓ | ✓ | | time_zone.standard_tz_abbreviation | ✓ | ✓ | | time_zone.standard_tz_full_name | ✓ | ✓ | | time_zone.is_dst | ✓ | ✓ | | time_zone.dst_savings | ✓ | ✓ | | time_zone.dst_exists | ✓ | ✓ | | time_zone.dst_start | ✓ | ✓ | | time_zone.dst_end | ✓ | ✓ | | time_zone.date | ✗ | ✓ | | time_zone.date_time | ✗ | ✓ | | time_zone.date_time_txt | ✗ | ✓ | | time_zone.date_time_wti | ✗ | ✓ | | time_zone.date_time_ymd | ✗ | ✓ | | time_zone.time_24 | ✗ | ✓ | | time_zone.time_12 | ✗ | ✓ | | time_zone.week | ✗ | ✓ | | time_zone.month | ✗ | ✓ | | time_zone.year | ✗ | ✓ | | time_zone.year_abbr | ✗ | ✓ | Use `/v3/ipgeo` when timezone information is required together with geolocation, ASN, network, security, or company data in a single request. Use `/v3/timezone` when detailed timezone metadata, formatted time values, or timezone conversions are required. ## Usage Limits The Timezone API is available on **both Free and Paid plans**. Free plan subscriptions include **up to 1,000 requests per day**. Paid subscriptions do not enforce fixed daily or hourly rate limits. If the monthly request quota is exceeded, requests continue and a surcharge may be applied depending on the subscribed plan. Requests made using invalid API keys or unsupported subscriptions return **HTTP 401 Unauthorized**. contact: name: IPGeolocation Support url: https://ipgeolocation.io/contact.html email: support@ipgeolocation.io termsOfService: https://ipgeolocation.io/tos.html license: name: Proprietary url: https://ipgeolocation.io/tos.html externalDocs: description: IPGeolocation Date, Time & Timezone API documentation url: https://ipgeolocation.io/documentation/timezone-api.html servers: - url: https://api.ipgeolocation.io description: Production security: - ApiKeyAuth: [] paths: /v3/timezone: get: operationId: lookupTimezone summary: IPGeolocation.io Timezone Lookup description: | Returns current date, time, and timezone information for a specific location or identifier.

Depending on the lookup method used, additional contextual information may also be returned in the response: - `location` object for IP address or location queries - `airport_details` object for IATA or ICAO code queries - `lo_code_details` object for UN/LOCODE queries If multiple lookup parameters are provided in the same request, the API resolves the timezone using the following priority order: 1. `tz` 2. `lat` and `long` 3. `location` 4. `ip` 5. `iata_code` 6. `icao_code` 7. `lo_code` If none of the lookup parameters are provided, the API resolves the timezone using the public IP address of the requesting client.
