Good Friday, as we can infer from its name, is observed on the Friday before Easter Sunday and is a religious holiday. It is also known as Holy Friday, Great Friday, Black Friday, or Easter Friday.It is observed across several countries and in Quebec employers can choose to give the day off either on Good Friday or Easter Monday. The actual celebration of Good Friday begins anywhere from 12:00-3:00 a.m. as it is said that during that time priests begin their observance of the most holy day.
