It works entirely offline by querying preprocessed polygon boundary data, making it suitable for applications that cannot rely on network calls or external APIs. The library emphasizes accuracy at timezone borders without geometric simplification, combining polygon data with H3-based spatial indexing for fast lookups.\n\nThe package supports modern Python versions (3.11\u20133.14) and offers two usage patterns: a simple global function for one-off queries, or a reusable instance for batch operations. It includes the full original timezone dataset with all timezone names for complete localization support, though a reduced dataset option is available for smaller memory footprint. Optional acceleration is available via Numba or a clang-backed point-in-polygon routine.","worth_installing":"Yes, if you need offline timezone lookup from coordinates. The package is actively maintained, has no known vulnerabilities, and ranks in the top 5000 PyPI packages by downloads. Medium install friction from 4 runtime dependencies is typical for geospatial work. Verify that ODbL data licensing aligns with your use case before deployment."},"id":"timezonefinder","links":{"html":"https://skillfed.io/packages/timezonefinder","md":"https://skillfed.io/packages/timezonefinder.md","pypi":"https://pypi.org/project/timezonefinder/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-13","license_spdx":null,"license_treatment":"unclear","name":"timezonefinder","python_support":"supports_current","summary":"python package for finding the timezone of any point on earth (coordinates) offline"},"popularity":{"monthly_downloads":6413680,"position":1915,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"8.2.5"}
