Thank you for a
quick reply, I'll try to make my question clearer.
If we count from
"noon" to "noon" a day, and count from equinox to equinox
as a year, how many days will be in a year ? Also, the answer would have to be
in whole numbers.
My two sons and
I are working on a project trying to figure out how
the ancients came
up with a seven day week.
Answer:
This is not an easy question to answer. A seven-day week does not
fit evenly into a 52-week year.
A year includes 365 solar days, except during a Leap Year when
there are 366 full solar days. How these days of the year are divided into
weeks (and months) was probably partly due to politics of the ancient era (specifically
Roman politics, in the case of months).
One seemingly obvious answer is that a seven-day week was
proscribed by God, in the account of creation from the Book of Genesis in the
Bible. However, it seems that the seven-day week was known before Christianity
became the dominant religion in the world.
Here is a short essay regarding the question of the origin of the
seven-day week:
