why is good friday a holiday

Good Friday is a Christian holiday commemorating the crucifixion and death of Jesus Christ. It is observed on the Friday before Easter Sunday and is a day of reflection, mourning, and penance for many Christians. The day is called "Good Friday" because, although it marks Jesus's suffering and death, Christians believe that this event was a crucial and ultimately "good" act of sacrifice for the forgiveness of humanity's sins. The term "good" historically meant "holy" or "pious," rather than joyful. Good Friday signifies Jesus's sacrificial death, which Christians believe brought salvation and reconciliation between God and humanity, and it is part of the spiritual journey culminating in the hope of resurrection celebrated on Easter Sunday. Many Christians observe the day with fasting, church services focusing on Jesus's suffering and crucifixion, and acts of charity and reflection.
