Hijri New Year, also known as Islamic New Year, is a significant holiday celebrated in Tunisia. This holiday marks the beginning of the new Islamic calendar year. The Islamic calendar, unlike the Gregorian one that is internationally observed, relies on lunar cycles. The Hijri New Year is the day that Prophet Muhammad migrated from Mecca to Medina, which was the pivotal event that started the Islamic calendar back in 622 AD.

Tunisia, as a predominantly Muslim country, observes the Hijri New Year with due reverence and solemnity. Unlike many other celebrations, this day is not characterized by vibrant festivities. Instead, it is a day of introspection, prayers, and remembrance of the Prophet's journey. Government offices and businesses are closed as it is a public holiday, while mosques hold special prayers, and some Tunisians may visit the cemetery to pay respect to the departed.

The significance of Hijri New Year extends beyond just marking a new year. It also symbolizes the central tenets of Islam – the faith, courage, and conviction that Prophet Muhammad exhibited during his migration from Mecca to Medina. While Tunisia and many other Islamic nations observe this day as a public holiday, the characterization and practice can vary depending on local culture and traditions. Nonetheless, it remains a day of crucial importance in the Islamic world.
