Hi ,

I want to have rolling 13 weeks in a calculated column i.e current week plus future 12 weeks. I have to show other data accordingly.I have a date column created in calendar table which is created from a date column from other table. When I am using the query editor filter "IN the next 12 weeks" , the data is coming incorrect. Please help me solving this issue.

Thanks

Hi @amkumar,

Please check the following steps as below.

1. Create a calculated table and create two calcualted columns in it.

```dimtime = CALENDAR(MIN('sales'[date]),MAX('sales'[date]))
```
`weeknum = WEEKNUM('dimtime'[Date])`
`year week = YEAR(dimtime[Date])*100+WEEKNUM(dimtime[Date])`

2. Create a new calculated table to get the result as we need.

```result = var yearweekt = YEAR(TODAY())*100+WEEKNUM(TODAY())
var yearweek12= YEAR(TODAY()+84)*100+WEEKNUM(TODAY()+84)
return
CALCULATETABLE(dimtime,yearweekt<=dimtime[year week] && dimtime[year week]<=yearweek12)```

For more details, please check the pbix as attached.

## Re: rolling 13 weeks in dax

Hi Frank,

I have a calendar table made out of a minimum and maximum due date from sales table. This table contains date for 2 quarters at one time and keep updating regularly eg Q4-18 and Q1-19, Q1-19 and Q2-19, Every quarter the dates update. I need to make a week column in the Calendar table which gives me current week and 12 weeks as the output irresepective of the year.
For example i want output  currently as Wk 46,47,48,49,50,51,52,53,01,02,03,04,05(I have dates from 1st oct-2018 to 31st march 2019 in calendar table).  Next week it should be changed to Wk 47till wk 06.

Thanks

Hi Frank,

Thank you for the solution. I have one more thing, i am not able to put the weeks in order as 13 weeks , like 46,47,48,49,50,51,52,53,01,02,03,04,05. It is coming now as 01,02,03,04,05,46,47.....53. Is there any way possible that we can put them in order as i have shown above.

Thanks
