Final answer:
Good Friday is the day before Easter Sunday and is a Christian holiday commemorating the crucifixion of Jesus Christ.
Step-by-step explanation:
The Friday immediately preceding Easter Sunday is known as Good Friday. Good Friday is a Christian holiday commemorating the crucifixion of Jesus Christ and his death at Calvary. It is a day of solemn reflection and is observed during Holy Week as part of the Paschal Triduum. It precedes Easter Sunday, the day Christians celebrate the resurrection of Jesus.The term "Good Friday" is somewhat paradoxical, as the word "good" in this context is thought to have originated from the Old English word "gōd," meaning holy or sacred. So, Good Friday is understood as a day of deep significance and holiness in the Christian calendar.
