## How to show week number per month?

I need to show how much volume shipped the first, second, third, and fourth week of each month. How can you assign a number (1-4 or 5) to each week of the month?  Thanks.

Hi cheid1977,

Please take a try with the formula below in a calculated column:

`weekinmonth = 1 + WEEKNUM ( 'Calenda'[Date] )-WEEKNUM( STARTOFMONTH ('Calenda'[Date]))`

This formula would work with the month level, which should be no calculated errors.

Please reply back if you need any further assistance on this topic.

Regards

Week = (DAY('Calendar'[Date])+2.5) /7

Si tu semana empieza en LUNES, la fórmula quedaría así:

`=1 + WEEKNUM(Calendario[Date];2)-WEEKNUM(STARTOFMONTH(Calendario[Date]);2)`

This is a good solution, but it only works if all the dates are unique.

In some cases, you would use a date column like invoiced date, start date, etc

I hope this code would help:

```Week Num =
WEEKNUM ( 'Your table'[Your Date column] )-('Your table'[Your Date column].[MonthNo]-1)*4```

OK, I didn't fully test this, but the general concept should work, you may have to tweak.

These are all columns:

```WeekN = WEEKNUM([Date])

MonthN = MONTH([Date])

Column 9 = IF([MonthN] = 1,1,([MonthN]-1)*4)

Column 5 = IF([Column 9]=1,1,[WeekN] - [Column 9] - 1)```

Hard to say without your data or some sample data. I think the right way would be to add a custom column to your Date table.
