What Are the Possibilities to Build Date Tables in Self-Service Environments?

Creating date tables in self-service analytics environments can be accomplished through two primary methods when a data warehouse source is not available. One approach uses DAX, starting with the CALENDAR() function and then adding various date attributes like year, month, and quarter using ADDCOLUMNS(). This DAX method also supports creating multilingual columns by specifying a locale in the FORMAT() function. The alternative technique involves using Power Query, which starts by generating a list of dates and then transforms it into a table, carefully handling complexities like leap years.
