How to choose
- Same job, not the same API. Each line is listed because it shares a crates.io category or keyword with chrono-tz-build; read its description before you swap.

- Check the last release against how fast you need fixes. For chrono-tz-build: is it still maintained?
Rules
Alternatives = tracked crates (top 1000 by downloads) that share a specific crates.io category (2 points each) or keyword (3 points each) with chrono-tz-build, most similar first; its own parts (same name prefix) and crates it depends on or that depend on it are left out, because those are companions, not substitutes. Real downloads = quiet-day median, crates.io data Oct 24, 2026. Built when we find 3 or more.
