Custom Week Number for specific Date Range

[SpiroswayGR]

Dear Community,

I would like to create a weeknumber for specific date range in 2 years :

Example : 

Start Date : 01/06/2019 to End Date : 05/11/2020

01/06/2019 to 07/06/2019 is Week1 

08/06/2019 to 15/06/2019 is Week 2 

......

XX/XX/2020 to XX/XX/2020 Week 145

My purpose is to create a weekly LINE chart on these specific dates for CY and LY (for same dates but 01/06/2018 to 05/011/2019).

Thanks in advance.

@Greg_Deckler  Looks like that i need sequential solution.

With this calendar table is possible to create sequential measure / column ?

@SpiroswayGR Yes, just start by creating columns for Year=YEAR([Date]) and Week=WEEKNUM([Date])

Create in your date table like

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date])+1
Week End date = DATEADD('Date'[Date],7-1*WEEKDAY('Date'[Date]),DAY)

Week = [Week Start date] & " to "& [Week End date]

use format on dates if needed

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

@amitchandak  Thank you for your effort.

There is a small progress but still not completed. These weeks are not sorted on my graph.

So is there any week to sort it with correct dates ?

Thanks in advance!!!

@SpiroswayGR , create week start as your sort column

@amitchandak  Thanks very much!!

Almost complete my solution but still 2 remaining things...

1st : Is it possible to show dates as "DD/MM/YYYY" instead of "MM/DD/YYYY"?

2nd : Is it possible to visualize on same weekly graph metrics for this week year and metrics for Last week year ? 

for example : Week for this year : 10/02/2019 to 17/02/2019 with Sum metric = 1000 and last year metric : 10/02/2018 to 17/02/2019 with sum metric : 500

Thanks again!!

Like

Week = format([Week Start date],"dd/mm/YYYY") & " to "& format([Week End date],"dd/mm/YYYY")

If you need set that as date format : https://community.powerbi.com/t5/Desktop/How-to-apply-UK-date-format-dd-mm-yyyy-in-Date-slicer/td-p/...
