Building Date Tables in Power BI & Power Query
Creating date tables is important in data analysis because they provide a structured way to analyze data over time. A date table includes every date within a certain range, along with details like the day, month, year, and whether it’s a weekend or holiday.
Having a date table allows you to easily perform time-based analysis, like comparing sales month-over-month, tracking trends over years, or understanding seasonal patterns. It also helps in joining your data with dates, making it easier to filter, group, and analyze your information based on specific time periods.
In short, a date table is essential for accurate and flexible time-related analysis, making your data more meaningful and your insights more reliable.
