St. Mark's Eve is observed on April 24, 2024. It is the day before the feast day of St. Mark. He was the Evangelist who founded the Church of Alexandra. In liturgical Christian churches, this feast of St. Mark is observed on April 25 of each year; thus St. Mark's Eve is April 24. In the old tradition people in England sat in the church on St. Mark’s Eve in total silence.
They believed that soon ghosts would appear of those whose live was up to end within one year. This superstitious and spooky custom has mostly died out though over the centuries. St Mark is often shown with a winged lion, which stands for his courage and monarchy.
