Learning: The holidays project prioritizes complete historical coverage in tests, verifying holidays from their first year of observance (e.g., 1853 for Finland) through future projections, rather than using shorter sliding windows.

Learning: The holidays library prioritizes full test coverage over performance in test suites. Modern library-wide standards favor comprehensive testing across all subdivisions and wide year ranges (e.g., 1803-2050 for France) to ensure thorough validation, even if it creates many test objects.

Learning: For the vacanza/holidays repository, defer to the ruff configuration and pre-commit checks for coding standards rather than making manual suggestions about line length or style issues. If the automated checks pass, the code follows the project's standards.

Learning: In the vacanza/holidays repository, the team prefers to manually update the country count in README.md when adding new countries, with tests in place to verify the count stays accurate. They are satisfied with this approach and do not want it automated.

Learning: Running `make pre-commit` in the holidays project can automatically fix common code style issues like whitespace in blank lines.

Learning: The holidays project uses `make pre-commit` test which includes `ruff` as the primary linter. If `ruff` passes, then Pylint warnings that don't appear in `ruff` are considered acceptable and can be ignored.

Learning: In the holidays repository, line length formatting should defer to pre-commit formatting checks rather than manual suggestions. If pre-commit allows it, the formatting is acceptable per project policy.

Learning: For the holidays Python library, when encountering line length or formatting issues, suggest contributors run `make pre-commit` to auto-format their files instead of providing specific manual formatting fixes like line splitting or noqa comments.

Learning: In the holidays project, test files follow a dual testing approach: individual methods test specific holidays across multiple years, while comprehensive year-specific tests (e.g., `test_2025`) verify all holidays for a specific year in a single assertion. Both approaches serve different testing purposes and complement each other.

Learning: For missing translator comments in .po localization files in the holidays repository, direct authors to run `make l10n` or `make check` commands instead of suggesting manual fixes, as these commands automatically handle translator comment generation.

Learning: For the holidays project, localization file formatting issues (like missing terminal periods in .po files) should be automatically fixed by running `make l10n` command (which is included in `make check`). Authors should be directed to use this automated tooling instead of manual formatting fixes.
