Summary

In this chapter, you have learned how to implement time intelligence when your calendar looks different to the standard Gregorian calendar that a Power BI model assumes.

For time intelligence analysis, you need a specific date table containing columns corresponding to the hierarchical levels in your calendar. In this chapter, we have implemented this as a calculated table.

To do actual time intelligence calculations, meticulous filtering over the date table and the various columns in it is needed. In particular, calculating results for "the previous year" requires a lot of different calculations, depending on what selections are made in the query context. All this evokes a renewed appreciation for what the built-in DAX time intelligence functions accomplish!

We closed this chapter off with an alternative to relative date filters in Power BI reports that is more flexible and can handle selections in non-standard calendars as well.
