Hi, your questions is quite ambigous. If you want to work with time intelligence, the first thing you need to know is that you need a Date Table containing one row for each day. Here you can find scripts to build one: https://blog.ladataweb.com.ar/post/185012464051/data-modeling-como-hago-una-tabla-fecha
After you relate the data from that table to the date on your table you can build this calculation like this:
Aggregation ( Table[Column] )
, DATEADD ( DateTable[DateColumn] , -N , Period)
Where period is year, month or day; -N is the number to go back in period; and "Aggregation" is sum, average, count, etc.
Hope this helps,
