How do i create a date table ?
sbowles The way I create a date table is as follows:
Click the insert new table button on the ribbon and copy in below:
DateKey = CALENDAR(DATE(2012,01,01),DATE(2017,06,30))
Then I add in a new column from the ribbon for each of the following:
Year = YEAR(DateKey[Date])
Month number = MONTH(DateKey[Date])
Month = FORMAT(DateKey[Date],"MMM")
Day = FORMAT(DateKey[Date],"ddd")
Week = WEEKNUM(DateKey[Date],1)
Quarter = "Q" & ROUNDUP(MONTH(DateKey[Date])/3,0)
MonthY = FORMAT(DateKey[Date],"MMM")&" " &DateKey[Year]
Day number = DAY(DateKey[Date])
Financial year = IF(DateKey[Month number]>6,DateKey[Year]+1,DateKey[Year])
Financial week = IF(DateKey[Month number]>6,DateKey[Week]-26,DateKey[Week]+26)
Total days = DAY(DATE(DateKey[Year],DateKey[Month number]+1,1)-1)
Financial month number = IF((DateKey[Month number]-6)<=0,DateKey[Month number]+6,DateKey[Month number]-6)
Financial month = FORMAT(DateKey[Date],"MMM")
Index = CALCULATE(COUNT(DateKey[Date]),ALL(DateKey[Date]),FILTER(DateKey,DateKey[Date]<=EARLIER(DateKey[Date])))
Monthy number = DateKey[Year]&DateKey[Month number]
I also include the following measures:
Measures
Current financial week = IF(WEEKNUM(NOW())-26<=0,WEEKNUM(NOW())+26,WEEKNUM(NOW())-26)
Current financial month = IF(MONTH(NOW())-6<=0,MONTH(NOW())+6,MONTH(NOW())-6)
Today = DATE(YEAR(NOW()),MONTH(NOW()),DAY(NOW()))
Then I can use these rolling filters:
Other formula
+/- 1 months = IF(AND(DateKey[Financial month number]>=[Current financial month]-1,DateKey[Financial month number]<=[Current financial month]),1,0)
Last 30 day = IF(AND(DateKey[Date]>=[Today]-30,DateKey[Date]<=[Today]),1,0)
Last week + two weeks = IF(AND(DateKey[Financial week]>=[Current financial week]-1,DateKey[Financial week]<=[Current financial week]+2),1,0)
Last 14 days = IF(AND(DateKey[Date]>=[Today]-14,DateKey[Date]<=[Today]),1,0)
+/- 30 days = IF(AND(DateKey[Date]>=[Today]-30,DateKey[Date]<=[Today]+30),1,0)
Hope this helps.

Thanks Giles , this is awesome and very helpful .. :-)
one more question ..
of all of these filters below i am getting the following error :
+/- 1 months = IF(AND(DateKey[Financial month number]>=[Current financial month]-1,DateKey[Financial month number]<=[Current financial month]),1,0)
"A single value for column 'Date' in table 'DateKey' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result."
sbowles Are you entering the formula as a measure or a column? It needs to be inserted as a column, I think this may be the issue.
