All Saints' Day, also known as La Toussaint, is a holiday observed in several parts of the world including Burundi, on the 1st of November annually. This holiday is dedicated to the celebration and honouring of all the saints in the Christian religion, known or unknown. This commemoration dates back to the early Roman Catholic Church which designated a single day to remember saints who did not have their own feast day.

In Burundi, a predominantly Christian country, All Saints' Day is a public holiday with many people attending special church services to pay homage to saints. It's a day when families come together to join in prayer and often involves visiting cemeteries to clean and decorate the graves of deceased loved ones in an act of remembrance and respect. Tribute is also paid to saints and martyrs through hymns, prayers, and various ceremonies.

Apart from religious services and rituals, this holiday also carries a social aspect. It is a time for families and communities to come together, nurturing unity and mutual respect among the citizens. It is also a moment for introspection and reflection on the lives of the saints and their contributions to Christian faith. Despite the thoughtful and solemn nature of the day, it also carries an air of celebration of life, legacy, and shared faith.
