FIRSTDATE

Description: The FIRSTDATE function in DAX (Data Analysis Expressions) is a fundamental tool for data analysis in various platforms that use this language, such as Microsoft Power BI and Excel. Its main purpose is to return the first date in a specified column, allowing analysts and data users to quickly identify the start of a temporal dataset. This function is especially useful in contexts where chronological analysis is required, such as evaluating trends over time or creating reports that depend on the temporal sequence of data. FIRSTDATE not only facilitates obtaining the earliest date but can also be combined with other DAX functions to perform more complex calculations and gain deeper insights. As a function that operates on date-type columns, it is essential that the data is correctly formatted to ensure accurate results. In summary, FIRSTDATE is a function that simplifies working with temporal data, enabling users to efficiently and effectively extract valuable information.
