Calculation for Calendar To-Date Prior Period

Hi! I am trying to calculate the value for the prior period in the following scenario:

 

The primary date range (CYTD): Jan 2 2022 - June 18 2022 

The previous time period range: Jul 18 2021 - Jan 1 2022

 

How would I calculate a value (e.g., Total Traffic) for the previous time period? I would like the calculation to be dynamic depending on where in the year I am (e.g., adaptable for the primary period selection of Jan 2 2022 - Dec 1 2022). 

 

I do have a date table with the following columns: Year (YYYY), Week No (1-52), Date (DD/MM/YYYY), SundayEnding, (DD/MM/YYYY), MonthNo (1-12), MonthName (e.g., Dec, Jan), Days in Month, etc.)

 

Thanks for any help in advance!

Hi, @allieg2830 

 

Can you provide some sample data or simple pbix files? Sensitive information can be removed in advance. What kind of expected results do you expect? You can also show it with pictures.

@allieg2830 ,

 

YTD =
var _max = if(isfiltered('Date'),MAX( 'Date'[Date]) , today())
var _min = eomonth(_max,-1*MONTH(_max))+2
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))

 

LYTD =
var _max1 = if(isfiltered('Date'),MAX( 'Date'[Date]) , today())

var _min =  date(Year(_max1) -1, month(_max1) , Day(_max1))
var _max= eomonth(_max,-1*MONTH(_max))
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))

 

 

or

 

same period based on date range
Last Period =
var _max =maxx(allseleceted(date),date[date])
var _min =maxx(allseleceted(date),date[date])
var datediff1 = datediff(_min,_max,day)
var _maxX = _max-datediff1
var _minX = _min -datediff1
return
CALCULATE(SUM(Sales[Sales Amount]),filter(all(date,date[date]<=_maxX &&date[date]>=_minX)))
