Date table addition

[Anonymous]

Hi Guys, 

I have a date table and i want to add a combination of the weeknumber - first day of that week - last day of that week. 

I have the columns Date and Weeknum, so this is enough to create the combination above. Someone any idea how to fix this?

Hi @Anonymous ,

Please check the formula below.

Column = 
var first = CALCULATE(MIN('Date'[Date]),FILTER('Date','Date'[weeknum]=EARLIER('Date'[weeknum])))
var last = CALCULATE(MAX('Date'[Date]),FILTER('Date','Date'[weeknum]=EARLIER('Date'[weeknum])))
return
"week"&'Date'[weeknum]&"-"&first&"-"&last

Result would be shown as below.

 

Best Regards,

Jay

Try

Week Start date = DATEADD('Date'[Date],-1*WEEKDAY('Date'[Date])+1,DAY)
Week End date = DATEADD('Date'[Date],7-1*WEEKDAY('Date'[Date]),DAY)
Week of = format(DATEADD('Date'[Date],-1*WEEKDAY('Date'[Date])+1,DAY),"mm/dd/yy"  & " - " & format(DATEADD('Date'[Date],7-1*WEEKDAY('Date'[Date]),DAY),"mm/dd/yy"))

Hi @Anonymous 

you can use the next statements for calculation:

FirstDayOfWeek = 'Date'[Date] - WEEKDAY('Date'[Date],2)+1

and

LastDayOfWeek = 'Date'[Date] - WEEKDAY('Date'[Date],2)+7

then use CONCATENATE function https://docs.microsoft.com/en-us/dax/concatenate-function-dax to get any combination you wish in desired format
