This year date value vs (this year date -364) value

[Anonymous]

Hi I have two tables, one is a date table, another one is a sales table. These two tables are connected through Order Date (Sales table) to Date (Date table)

I have a measure as below, which gives me the value of fiscal year 2019 total sales $.

This Year Sales = calculate(sum('Sales Table'[Sales $]),filter(Date Table,Date Table[Date] <= Date Table[Fiscal Year 2019 End Date] && Date Table[Date] >= Date Table[Fiscal Year 2019 Start Date]))

In my design view, when I select a specific date from date table, the above measure will give me the sales $ for that date in 2019.

Now I would like also have another measure to give me the sales $ for (same date -364) in 2018. 

For example, when select 1/1/2019, this year sales measure gives me the sales $ on 1/1/2019, and I would like to see the sales $ on (1/1/2019 -364) = 1/2/2018 from the new measure.

I have tried to use DAX with sameperiodlastyear, which this one gives me the value for 1/1/2018 instead of 1/2/2018. I think this sameperiodlastyear calculation is based on date minus 365, but I would make it as date minus 364.

Thanks in advance!!

@Anonymous ,

You may try DATEADD() function instead:

DATEADD(<dates>,<number_of_intervals>,<interval>)
