If you want to get real technical, it was the Romans rather than the Jews that, in the first century, numbered the days of the week and decided that Sun's day was going to be the 1st day and Saturn's day was the seventh. The seventh day sabbath keepers are using a pagan calendar to count the days, but the church has also used this Julian calendar with that numerical system for nearly 1800 years. The monkey wrench in all this started in 1752, when the United Kingdom and North America switched from the Julian calendar to the Gregorian calendar. By Parliamentary decree, the day immediately after September 2nd was September 14th and 11 days were skipped. (There were even riots because people thought 11 days had been taken off their lives and it was a campaign issue in the British election of 1755.) Therefore if you do the math and put back the taken days, Saturday worshippers who think they are following the Bible by worshipping on the seventh day according to the Roman calendar, are really worshipping on the previous Tuesday, which is the third day of the week. And Sunday worshippers who think they are worshipping on the first day of the week are really worshipping on the previous Wednesday, the fourth day of the week. Of course, this doesn't take into account the additional drift that has taken place over the past 2 centuries. In the intervening period between 1752 and today, the difference between the Julian calendar used by the early Church and our current calendar has grown to 13 days. A new day is added every 125 years. So I think this means that in 2006, what we call Saturday which is the seventh day, is really the previous Sunday, the first and it will all even out by 2100. It is also very, very important to remember that this doesn't apply if you live in Alaska, which had two Fridays in a row: Friday October 6th immediately followed by Friday October 18th, when they switched from the Russian calendar to the US calendar after the US purchased Alaska from Russia in 1867. If you do the math there, the Alaskans are all only one day off with Saturday really being Sunday and the week's first day. So seventh day worshippers in Alaska are really worshipping on the first day and Sunday worshippers on the second day. And it is important to remember that none of this applies in Scandinavia, Greece, Russia or other countries since they had to drop different numbers of days to adopt the Gregorian calendar. They would all be worshipping on completely different days: the 1st, 4th, 5th, and 6th.
