All Saints' Day, or 'Todos los Santos', as it is known in Spain, is celebrated annually on November 1st. Unlike the way All Saints' Day is observed in some countries where it merely services as a time to honor all saints, known and unknown, in Spain and other Hispanic cultures, it is more a day for families to remember and pay tribute to their deceased relatives. The day is marked by the nation-wide holiday where schools, businesses, and government offices are closed.

The practices held on this day vary across regions in Spain. However, a common tradition is visiting cemeteries to clean and decorate the graves of departed loved ones with flowers and candles. Mass services are held, and prayers are offered for the souls of the deceased. It is a public solemn occasion, yet it doesn't mean sadness but a silent celebration of life and the remembrance of loved ones who have passed away.

Another significant tradition on All Saints' Day in Spain is the preparation and eating of special foods. In particular, 'Huesos de Santo' or 'Bones of the Saint' and 'Panellets' are traditional sweets prepared during this period. These treats are enjoyed while spending time with family members. Also, in some parts of the country, people gather to sing and share stories about their deceased relatives. Despite the holiday's religious undertones, it has a strong cultural significance in Spain, symbolizing respect and honour for the deceased.
