## Re: Derive MonthWeek field from the date

Week numbers are a bit tricky as they can span years and also that the week numbers aren't calculated the same across different countries.

So for instance in India week #1 of 2016 starts on the 27th of December of 2015 and ends on the 2nd of January 2016 whereas in the UK week#1 of 2016 starts on the 4th of January 2016 and ends on the 10th of January 2016.

However you can use the Week() function will always return a number between 1 and 52 or 53 (depending on country settings). WeekYear() function will indicate which year the week belongs to.

Basically this is what you have to do:

Dual( Month(Date) & 'W' & Week(Date) , WeekYear(Date) & Week(Date) )

## Re: Derive MonthWeek field from the date

Weeks are not divisible into months. You will most of the time have a week at the beginning and the end of the month that will not be seven days. Comparing the sales numbers for a week containing fewer than seven days with those that have seven days would not be very correct would it? How would you want to resolve that?
