Learning: In the holidays project, .po file header comments use the format "# [Country] holidays." for default language files (without trailing hash) and "# [Country] holidays [locale] localization." for non-default language files (also without trailing hash).

Learning: In the holidays library, when a locale file matches the country's default language (e.g., pt_PT for Cape Verde), the msgstr fields should be left empty. Only non-default language files should have filled msgstr fields with translations.

Learning: In the holidays project, .po file header metadata updates (version numbers, revision dates, translator information) are legitimate changes when part of localization work and don't require `make l10n` regeneration. The `make l10n` command is primarily for formatting fixes and missing translator comments, not for intentional metadata updates.

Learning: In the holidays library localization pattern, when a locale file matches a country's default language (e.g., pt_PT for Cape Verde), the msgstr fields should be left empty. Only non-default language locale files should have translations in the msgstr fields.

Learning: In the holidays project, .po files follow a standard formatting convention where there is always a blank line after the metadata header section (after the "X-Source-Language" line). This blank line separates the header from the actual translation content and should not be removed.

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 project, msgid fields in localization files contain strings in the entity's default language (as defined by default_language attribute), not English source strings as in standard gettext implementations.

Learning: In the holidays library, localization files have a specific structure: message comments are in standard English (en_US) describing the holiday, while actual translations (msgstr) should use the locale-specific terminology (e.g., en_CI for Ivory Coast English). For example, "Night of Power" in standard English is translated as "Lailatou-Kadr" in Ivory Coast English.

Learning: In the holidays package, explanatory comments about year restrictions or policy context should be placed above conditional blocks or at method level, never directly above holiday name comments that precede tr() function calls, as this would include the explanatory text in .po localization files when running `make l10n`.

Learning: In the holidays project, snapshot files (like snapshots/countries/TL_COMMON.json) are auto-generated when running `make snapshot` and should not be manually edited. Semicolons (;) in holiday entries are used as separators when multiple holidays occur on the same date.

Learning: The holidays library uses a standard file header format across all country implementation files consisting of a comprehensive comment block with project description, authors, website, and license information. Country files do not use module-level docstrings but instead rely on this header format followed by class-level docstrings.

Learning: In the holidays project, .po files should use the full multi-line header format including the project description, authors, website, and license information, rather than a single-line comment format.
