The short answer
Yes. Yennayer, the Amazigh New Year, has been an official public holiday in Morocco since 2024. The next one, Amazigh year 2977, falls in mid-January 2027, on 13 or 14 January; sources differ, so check the exact day. Banks and offices close, sites stay open, and it is felt most in the Atlas villages.
In more detail
Yennayer marks the start of the Amazigh (Berber) year and has been celebrated for centuries in rural Morocco, long before it became a national holiday. Our calendar notes it as an official holiday since 2024, with the 2027 date still to confirm.
The day is mostly a family occasion. A common dish is couscous with seven vegetables, and in the Atlas villages near Marrakech it is marked more strongly than in the city. Public celebration of Amazigh culture has grown in recent years.
For a visitor, the practical effect is small: government offices and banks shut, while riads, restaurants and the main sights carry on. It falls in a calm part of the year, after the New Year rush and before the Moroccan school break at the end of January, and it pairs well with a mountain day. If you want to see it marked, ask your guide whether a village family or a local association is holding a gathering.
