Have you ever struggled to create the perfect Date table in Power BI or Excel? Messy calendars, complex relationships, and time-consuming formulas can make it a frustrating experience. I’ve developed an advanced Power Query solution to streamline date management – and I’m eager to share it with the community!
Why You Need This Query
- Effortless Date Modeling: My query generates a comprehensive Date table, complete with columns for year, month, quarter, week, fiscal periods, and more.
- Enhanced Time Intelligence: Analyze your data seamlessly across different time periods with pre-calculated aggregations.
- Customization: Adapt the query to fit your company’s specific calendar requirements.
- Plug-and-Play Simplicity: Forget complex DAX formulas; connect this date table to your data model, and you’re ready for advanced analysis!
How to Implement – A Quick Guide
- Copy the Query: I’ll provide the full M code for easy copy-pasting.
- Open Power Query: In Excel or Power BI, select “Get Data” -> “Blank Query.”
