Is It Sunday The Exact Church Day?

Each and everyone believer or not have their own church day observance. I don't know to the unbelievers what day they consider for their church day. Regardless of religion people might think what day best for them to go to church. Several people already debated about what is the exact day that a man will go to church. Pastors, Lay ministers, priest and church elders have their own interpretation on the exact day for church service.

Priest mostly they are in favor of Sunday's because it's the beginning of the week. But some think it's an end of the week. Gregorian calendar only showing that way but other religion like Islam and Jews have their own calendar dates that starts with different day.

Pastors from Seventh Day Adventist insisted that Saturday is the day for us to go church as per the Bible Rule. If all we based in the Bible it takes many days to clarify things and a big debate might happened.

Some people consider any day depending on the their convenience. I mean the schedule of their church service are not fixed in any day of the week. They don't have any belief that they follow what other church do like Sabath or Friday. It depends only on their agreed schedule.

How your guys, what do your think the best day for church service in your behalf?
