A date table typically includes columns like Date, Day, Month, Quarter, and Year, along with other relevant information. Creating a date table in Power BI is a common practice to enhance the capabilities of time-based visualizations and analytical functions. You can generate a date table using the "New Table" feature in Power BI and populate it with a range of dates. Once created, this table can be linked to other tables in your data model to enable time-related calculations and analysis. Why is a date table important in Power BI   ? A date table is important in Power BI for several reasons: Time Intelligence Functions:  Power BI has specific functions designed for time-related calculations, such as calculatin...
