Good Friday, known as 'Pitkäperjantai' in Finnish, is a major religious holiday recognized in Finland, coming as it does in the Holy Week leading up to Easter Sunday. The day holds deep significance to Christians in the country as it commemorates the crucifixion of Jesus Christ, marking it as a day of sorrow and mourning. During this day, church attendance is a widespread practice as many observe special services that often include passion plays or vivid descriptions of Christ's crucifixion.

Additionally, Good Friday in Finland is identified by several unique customs and traditions. A common practice called 'Virpominen' often takes place during this period. This old Finnish tradition involves children dressing up as witches and going from door to door in their neighborhoods, blessing homes while wishing people health and prosperity. In return, they receive treats or small amounts of money. Although traditionally taking place on Palm Sunday, in recent years, it's been increasingly associated with Easter Friday.

Apart from religious occasions, Good Friday in Finland also signifies a time for family gatherings and contemplative peace. The day is a public holiday, which means many businesses are closed, and people have the day off work allowing them to spend quality time with their loved ones. The celebration of Good Friday mirrors the devout and reserved nature of the Finnish people, where the focus lies more on reflection and familial closeness as opposed to grand feasts and noisy celebrations.
