Learning: In the holidays library implementation, explicit holiday dates (like Diwali in Fiji) are only defined for historical years with official sources (2016-2025). Future dates beyond the explicitly defined range are automatically calculated by methods like `_add_diwali`, which provide approximations when official dates aren't yet available.

Learning: For holiday tests in the vacanza/holidays project, structure tests by individual holidays rather than by years. Each test method should focus on a specific holiday and test it across multiple years (from start_year through 2050) using helper methods like `assertHolidayName`. For fixed holidays, use generators like `(f"{year}-01-01" for year in range(1991, 2051))`. For movable holidays, specify individual dates for specific years followed by a range check.

Since in the Islamic calendar days begin at sunset rather than midnight, methods like `_add_laylat_al_qadr_day` and `_add_mawlid_day` correctly calculate these dates without requiring an additional day offset in the implementation, following the same pattern as in the Ivory Coast implementation.

Learning: In the holidays library, date dictionaries that map years to specific dates (like queens_birthday_dates, spring_bank_dates, thanksgiving_day_dates, etc.) are typically defined within the _populate_public_holidays method rather than as module-level constants. This is the established library-wide pattern seen across multiple country implementations including United Kingdom, United States, Sri Lanka, and others.

Learning: In Guyana's holidays implementation (holidays/countries/guyana.py), Emancipation Day should be implemented as a fixed-date holiday on August 1st with weekend observance rules, not as the first Monday of August. This is confirmed by official Guyana Ministry of Home Affairs sources.

Learning: Holiday name comments directly above tr() function calls in the holidays package should only contain the holiday name itself (e.g., "# Independence Day.") without any additional context, dates, or historical information.

Learning: In the holidays library, the standard approach for organizing static holidays is to use separate dictionaries for different categories (like `special_government_holidays`, `special_mandatory_holidays`, and `special_public_holidays`), which are utilized by syntactic sugar methods to pick up the appropriate holidays based on the selected category.

Learning: The en_TL (English for Timor-Leste) localization for holidays intentionally uses "World" instead of "International" (e.g., "World Labour Day") to maintain accuracy with official Timor-Leste government sources, even though code comments and other localizations like en_US use "International".

Learning: In the holidays library, `_CustomIslamicHolidays` subclasses follow a consistent pattern of NOT having docstrings. They go directly to defining date dictionaries, as evidenced by Malaysia, Singapore, UAE, and dozens of other country implementations.

Learning: The holidays library provides helper methods `_add_holiday_2nd_sun_of_may()` and `_add_holiday_3rd_sun_of_jun()` for adding holidays on the 2nd Sunday of May and 3rd Sunday of June respectively. These methods are used across multiple country implementations including Latvia, Finland, Belarus, Malaysia, Madagascar, and Cape Verde.

Learning: In the holidays library, method names like `_add_holiday_2nd_tue_of_feb()` and `_add_holiday_1st_sun_of_mar()` use calendar constants like FEB, TUE, MAR, and SUN internally through parent class implementations even when these constants don't appear directly in the file.

Learning: In Christmas Island, ANZAC Day (April 25) follows the same observed holiday rules as other holidays, using the SAT_SUN_TO_NEXT_MON rule to move to Monday when it falls on a weekend. The implementation correctly uses `_add_observed` wrapper around `_add_anzac_day`.

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.

188-190: Addition of 2025 Independence-Day joint holiday looks correct

"2025-08-18" is inserted in chronological order, maintains the existing pattern for Independence-Day joint holidays, and is properly covered under the GOVERNMENT category test. No further changes required.

1127-1130: Snapshot entry correctly captures the new joint holiday

The generated snapshot now contains
"2025-08-18": "Independence Day Joint Holiday",
accurately reflecting the code update and keeping the dataset in sync.

641-641: Good addition of source documentation.

The new reference URL provides proper documentation for the August 18, 2025 holiday decision, which aligns with the library's practice of maintaining comprehensive source references.


673-674: Well-implemented translation constant.

The new independence_day_joint_holiday constant follows the established naming pattern and provides proper Indonesian translation with English fallback. This centralizes the holiday name and makes maintenance easier.


734-734: Smart refactoring to use the new constant.

Replacing the hardcoded string with the new independence_day_joint_holiday constant improves consistency and maintainability. The 2006 entry now uses the same naming as the 2025 entry.


882-882: Correct implementation of the new 2025 holiday.

The August 18, 2025 Independence Day Joint Holiday is properly added to the special government holidays using the new translation constant. This matches the PR objective perfectly.
