The name is probably a variation of God's Friday. American Good Friday customs include attending church services. The Saturday when Christ rested in the tomb is commemorated in some churches by an Easter vigil and the lighting of Paschal candles. Easter Sunday begins early for many Americans. Many people attend sunrise services, a custom brought to this country by European settlers.
Easter is a family day.
After services, relatives get together for Easter dinner that last from noon until three o'clock in the afternoon. After I've followed the ELI program for two months, I think my English has improved much especially in listening and speaking.
