Algeria operates on two concurrent calendars. The Gregorian calendar structures government and commercial life. The Islamic lunar calendar determines religious observances, shifting approximately 11 days earlier each Gregorian year. Most Algerian festivals follow the lunar calendar, making fixed-date planning impossible beyond the current year. The Ministry of Religious Affairs announces exact dates months in advance based on moon sightings confirmed by the National Commission for the Sighting of the New Moon, established in 1964 under presidential decree.
Ramadan structures Algerian public life for one lunar month annually. Fasting occurs from dawn to sunset. Iftar, the evening meal breaking the fast, begins when the Maghreb call to prayer sounds, typically between 18:00 and 20:00 depending on season. Streets empty 30 minutes before iftar as families gather. Restaurants close during daylight hours, though some hotels serve non-fasting travelers in screened areas. The Grand Mosque of Algiers, opened in 2019 with capacity for 120,000 worshippers, hosts nightly tarawih prayers lasting 90 minutes after the Isha prayer. Cafés reopen after 22:00, remaining active until suhoor, the pre-dawn meal taken before the Fajr prayer around 04:00. Banks reduce hours to 08:00-14:00. Government offices operate 09:00-15:00. The national productivity shift during Ramadan has been documented in economic studies showing GDP contraction of approximately 0.3 percent during the month since 1999. Laylat al-Qadr, the Night of Power commemorating the first Quranic revelation, falls on one of the last ten odd nights of Ramadan, most commonly the 27th night. Mosques fill capacity on these nights. The Ketchaoua Mosque in Algiers, originally built in 1612 and reopened after renovation in 2018, records attendance exceeding 15,000 on the 27th night.
Eid al-Fitr marks Ramadan's conclusion. The exact date depends on moon sighting. Families attend communal prayer at dawn in mosques or designated outdoor prayer grounds called musallahs. In Algiers, the Martyrs' Memorial esplanade accommodates overflow crowds exceeding 50,000. Men wear new or freshly laundered gandouras. Women dress in traditional kaftans or modern modest clothing. Children receive gifts and new clothes. The holiday extends three days officially. All government offices and most businesses close. Families visit in hierarchical order: younger members call on elders, then neighbors, then friends. Pastries specific to Eid include dziriettes, round butter cookies from Algiers, and makroudh, semolina cakes filled with date paste and fried, originating in Biskra. Zakat al-Fitr, the obligatory charity, amounts to approximately 120 dinars per person as of 2024, equivalent to 3 kilograms of staple grain. The National Algerian Zakat Fund, established in 2003, collects and distributes these contributions. Streets host informal football matches. Public parks fill. The celebration carries less commercial inflation than in Gulf countries. Most gift-giving involves money in envelopes, typically 500 to 2,000 dinars for children from relatives.
Eid al-Adha occurs 70 days after Eid al-Fitr. This holiday commemorates Ibrahim's willingness to sacrifice his son. Families who can afford it slaughter a sheep, goat, or cow after the morning prayer. The National Office of Livestock estimates 5.2 million sheep slaughtered during Eid al-Adha 2023. Urban families often purchase animals weeks in advance, keeping them on rooftops or in apartment building courtyards. The Ministry of Agriculture publishes price ceilings annually. In 2023, sheep prices ranged from 40,000 to 80,000 dinars depending on weight and breed. The Ouled Djellal breed from Biskra commands premium prices. Slaughter occurs in streets, courtyards, designated municipal areas. The meat divides into thirds: one for the family, one for relatives, one for the poor. Preparation methods vary regionally. In Algiers, the liver grills immediately as mid-morning celebratory food. In Constantine, boulfaf wraps grilled offal in caul fat. Tlemcen families prepare chorba loubia, white bean soup, as the first meal. The holiday extends four days officially. Livestock markets in Djelfa, M'Sila, and El Oued operate at peak capacity the week prior, with daily sales exceeding 100,000 animals according to Ministry of Commerce statistics.
Mawlid al-Nabi celebrates the Prophet Muhammad's birth on the 12th day of Rabi' al-Awwal, the third lunar month. State recognition came in 1964. The day is an official public holiday. Observance intensity varies by region. In Tlemcen, families visit the Sidi Boumediene Mosque, built in 1339, which houses the tomb of Abou Madyane Chouaïb, a 12th-century Sufi scholar. Attendance exceeds 30,000 on Mawlid. Constantine hosts processions through the old city culminating at the Sidi M'Cid Mosque. Algiers sees less public activity, primarily limited to private family gatherings. Mosques organize lectures recounting the Prophet's biography. Traditional chanting groups called madih perform in zawiyyas, Sufi lodges. The practice concentrates in western Algeria, particularly around Mostaganem and Oran. Families prepare couscous with tfaya, caramelized onions and raisins. Some distribute tamina, a sweet paste of toasted flour, butter, and honey, to neighbors and mosques. The Ministry of Religious Affairs estimates 15,000 mosques hold special programs on Mawlid. Commercial activity remains normal outside the holiday hours.
Islamic New Year, the first day of Muharram, passes with minimal public observation in Algeria. Government offices close. Banks close. No traditional festivities exist. Some families prepare special meals, but this varies by household without regional or national patterns. The day marks administrative calendar turnover for Islamic institutions.
Ashura, the 10th of Muharram, holds greater significance, particularly in Berber communities. The day commemorates multiple events in Islamic history, including the day Musa crossed the Red Sea and the martyrdom of Hussein at Karbala in 680 CE. Algerian observance leans toward the pre-Islamic Berber tradition rather than Shia mourning practices. Families prepare chekhchoukha, a dish of torn flatbread with chickpea stew, considered auspicious. Children receive dried fruits, nuts, and coins. In M'Zab Valley, the Ibadi Berber community in Ghardaïa observes with communal prayers and charity distribution. Some families fast, following the hadith recommending fasting on Ashura and the day before or after. No processions occur, distinguishing Algerian practice from Shia-majority countries. Many Algerians consider Ashura primarily a children's holiday. Toy vendors appear in urban centers selling small drums and traditional toys in the week preceding.
