This is generally considered to be around eight weeks. Most months have either 30 or 31 days, apart from February which has 28. On average, two months will be considered to be around eight to nine weeks, as the average month has roughly four weeks.
- What is a month exactly?
One month is a unit of time that is used with calendars. The month was first invented and used in ancient Mesopotamia. Back then, the month was used as a natural period that related to the motion of Earth's moon. 'Month' and 'Moon' are, hence, cognates - which seems sensible given you now have a new understanding of the word 'month'. - The traditional concept of a month first arose with the cycle of the moon's phases. For instance, months, or lunations, are actually synodic months and last approximately 29.53 days.
- From found and excavated tally sticks, researchers have been able to deduce that people back then counted the days in relation to the Moon's phases even as early as the Paleolithic age. The aforementioned synodic months, which are based on the Moon's orbital period, today remain the basis of most of the calendar months. These months are used to divide the year, and they divide it by 12.
- The most two months could actually be are 62 days, and the least that two months combined could be 59 days. This of course means there is a difference between the amount of weeks between two months, but in general, you can expect it to remain about the same as the difference between the most (62) and the least (59) is only three days - that's less than one week. For information about this, and the lunar cycle, then you can visit Wikipedia. There is a huge article available that talks about the months, their history and how they work exactly in the man made concept of years and time.
