Why Time Intelligence Fails
Power BI provides a very strong time intelligence, with a great list of functions around. But still, Time Intelligence fails. This is because the setup is not correct.
Five key points to remember
Use Date Table (Join with Fact Date)
Date table is marked as a date table
Use columns from date table
Date does not have a timestamp
Date table has all dates
I have discussed these in details in my Video at YouTube

Data and its analysis is the need of the hour. Business Intelligence and Analytics tools are enablers for data driven culture. Often comparing data between two time slices is commonly sought after. Say, for example, one would like to compare sales of this year vs last year. Or for a custom period like sales of this year Christmas season vs last year Christmas season.
