Info about "Month"

A month forms the time span of 28, 29, 30 or 31 consecutive days. Due to its varying length, the month is not a physical unit of time and thus not a unit of time in the international SI system of units.

To enable a general conversion (e.g., into seconds, minutes or years), the average length of the month in days is defined: Since a year comprises 12 months, a normal calendar year with 365 days results in a month length of 365 / 12 = 30.416667 days

In astronomical terms, a month is defined as the period of one complete revolution of the moon. Depending on the definition, the lunar month is a little more than 28 days on average.

Info about "Week"

In today’s culture, the “week” is a common unit of time comprising seven days. However, it is neither a legal unit nor a physical unit of time in terms of the International System of Units(SI), compared to seconds, minutes or hours.

Here, 1 week is equivalent to 7 days, 1 day is therefore equal to 0.14286 weeks.

Historically, the combination of seven days into a unit of one week can be traced back to the length of one moon. The entire phase from full moon to another full moon lasts slightly longer than 28 days. This is divided into four lunar phases (full moon - waning crescent - new moon - waxing crescent - full moon), which suggests the division of the 28 days into four weeks of seven days each.
