Um, there were 7 days of the week in Jesus day and there are seven days of the week today.
Does “Rome” have that wrong? Lol
There is zero chance that you would understand my answer since you lack the brain power to comprehend post #50, so run along and follow that broad road to that wide gate which Rome endorses.
Rome has it wrong because Friday night and Saturday night only equals TWO nights, not the THREE that Jesus Himself said He’d be in the earth.
The Gregorian calendar has it wrong. Gregory picked the wrong day to assign to the time of Jesus death.
