Which day is the seventh day of the week?
The calendar that we use today was instituted by Pope Gregory XIII in 1582AD, replacing the Julian calendar that had been in use since 45BC.
The Gregorian calendar that we are using today actually shifted the week by 10 days so the Sabbath day that was observed in the Julian calendar is not the same anymore.
Closer to home in Samoa, when the dateline was shifted some years back to the east, Saturday became Sunday. The Sabbath worshipers in Samoa are now actually worshiping on the Sunday.
