public class ProphetsBirthday extends AbstractObservance
Observance of the Prophet's Birthday (Mawlid an-Nabi), commemorating the birth of the Prophet Muhammad (12 Rabi' al-Awwal AH).

Dates are determined by official moon sighting and cannot be computed algorithmically. Dates for 2024–2026 are sourced from official UAE Securities and Commodities Authority (SCA) and Saudi Exchange (Tadawul) holiday announcements. Dates for 2027–2055 are projected from the Umm al-Qura tabular Islamic calendar; verify against official announcements as each year is published.

Note: Saudi Arabia does not officially observe Mawlid as a public holiday for financial markets; include only when the relevant exchange/regulator confirms it as a closure day.

Date data is loaded at runtime from mawlid-{countryCode}.csv in this package, where countryCode is the ISO 3166-1 alpha-2 country code in lower case (e.g. ae, sa).
