Add `ChristianHolidays::_add_saint_martins_day` method #3023

PPsyrius · 2025-10-28T02:44:37Z

Proposed change

I initially planned to include this in my PR for #3022, but since @KJhellico has also been working on that, I’m splitting this change into a separate PR for better atomicity.

Type of change

New country/market holidays support (thank you!)
Supported country/market holidays update (calendar discrepancy fix, localization)
Existing code/documentation/test/process quality improvement (best practice, cleanup, refactoring, optimization)
Dependency update (version deprecation/pin/upgrade)
Bugfix (non-breaking change which fixes an issue)
Breaking change (a code change causing existing functionality to break)
New feature (new holidays functionality in general)

Checklist

I've read and followed the contributing guidelines.
I've run make check locally; all checks and tests passed.

Summary by CodeRabbit

Refactor
- Introduced a dedicated method for handling Saint Martin's Day (November 11) across the holiday system, improving code organization and maintainability for multiple countries including Italy, Sint Maarten, and Austria.

Walkthrough

Introduces a dedicated _add_saint_martins_day method in the ChristianHolidays group and replaces direct _add_holiday_nov_11 calls with _add_saint_martins_day in Italy, Sint Maarten, and Austria country definitions.

Changes

Cohort / File(s)	Summary
New method `holidays/groups/christian.py`	Adds `_add_saint_martins_day(self, name) -> date` which delegates to existing `_add_holiday_nov_11(name)` to register November 11 (Saint Martin of Tours Day).
Method adoption `holidays/countries/italy.py`, `holidays/countries/sint_maarten.py`, `holidays/countries/austria.py`	Replace direct `_add_holiday_nov_11(...)` calls with `_add_saint_martins_day(...)` for the November 11 Saint Martin holiday.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

Small, consistent refactor across a few files.
Areas to spot-check: holidays/groups/christian.py new method docstring/typing and each country file's call sites for correct parameters/translation usage.

Learning: In the France holidays implementation, the _populate_subdiv_57_public_holidays() (Moselle) and _populate_subdiv_6ae_public_holidays() (Alsace) methods are functionally identical, both adding Good Friday (≥1893) and Saint Stephen's Day (≥1892) with the same legal references from August 16th, 1892. Therefore, for the deprecated "Alsace-Moselle" subdivision, calling either method produces the same result.

File: holidays/countries/french_southern_territories.py:41-44
Timestamp: 2025-06-18T10:07:58.780Z
Learning: Territorial holiday classes that inherit from parent countries (like HolidaysAX from Finland, HolidaysSJ from Norway, HolidaysTF from France) follow a standard pattern of silently overriding self.subdiv in their _populate_public_holidays() method without validation, as this ensures they always use the correct subdivision code for their territory regardless of user input.

127-127: Clean refactoring.

Replacing the generic _add_holiday_nov_11 with the semantic _add_saint_martins_day improves clarity and maintains consistency with other saints' day methods like _add_saint_josephs_day. Functionally equivalent, no issues.
