All Saints' Day is a Christian observance dedicated to honoring all the saints of the church who have ascended to heaven. In Western Christianity, it is commemorated on November 1, while in Eastern Christianity, it is observed on the first Sunday after Pentecost.

This day serves as a time for remembrance and reverence for departed souls. In Poland, for instance, individuals visit cemeteries to illuminate candles and place flowers on graves as a way of paying homage to the departed.
