*week*is fairly simple. It is a seven day period beginning on a Sunday. Therefore the first "week" of this month was not a complete week. If you want to define

*week*as any number of days, so long as it starts the month, then the definition changes. For example, in June (next month) June 1st happens on a Saturday, so the first Sunday in June is June 2. Would you still want the singleton June 1 to count as a whole week?

What is your definition of

*week*?
