Longcase clock by Luke Smyth of Yoxford, England c. 1790
Ever wondered why there are seven days in a week?
Our calendar originates from a mixture of pagan1 and mythical beliefs, including:
It is convenient for followers of a religion to conform to society norms, even when there is no religious connection. For example, our way of measuring time (hours, minutes and seconds) are based on an early Babylonian system, and our modern calendar is based on pagan practices and astrology.
But whether we are 'religious' or not, we do not think of the calendar as a pagan thing; it's merely a means to measure time, using things called 'days' and 'months'. When we see on the church notice-board: 'Sunday Worship', it doesn't mean that people will gather on that day to worship the sun. (See also Sun Cross.)
Church-goers do not put their faith or trust in the sun or any other pagan thing to gain favour of the gods. They do not worship the Christmas tree, and the Christmas tree is not necessary to celebrate Christmas. If someone believes a Christmas tree has some mystical power, it is the value that person has placed on it. The same goes for the Bible, the cross, and all the other items adopted by Christians that have a pagan origin.
