How Are Weekend Mass Times Set?
How do parishes decide weekend Mass times? Are there any guidelines in canon law or the General Instruction of the Roman Missal?
Sunday Masses may be any time from 4 p.m. Saturday evening to Sunday before midnight (which sometimes happens at colleges and in Latin countries, where 9 p.m. Sunday Masses are not unheard of). That is the only norm there is, taken from canon 1248, 1 in the Code of Canon Law. The 4 p.m. vigil time is customary, although there are those who would argue for 3 p.m. All this applies also to holy days that do not fall on Sunday.
