• Because the Gregorian Calendar follows the phases and moon phases, a week is 7 days. It takes the Moon 29.5 days to go through its phases. However, this is not a good number to use to calculate a time period. Babylons rounded down this cycle to 28 days, and divided it into 4 period units with 7 days each. There are four weeks in a month.
• The English language names Saturday, Sunday, and Monday after three of the gods Saturn, Sun, and Moon. Other days are named after Norse or Germanic gods.
• The international standard states that the week begins on Monday. However, the US norm still considers Sunday to be the first day.
