Datediff dax | date dax in power bi
1) DATE Function:
Purpose: To create a date value from individual year, month, and day components.
Syntax: DATE(year, month, day)
Example: DATE(2024, 8, 16) creates the date August 16, 2024. This is useful when you want to build a specific date using separate year, month, and day numbers.
2) DATEVALUE Function:
Purpose: To convert a date in text format into a proper date value.
Syntax: DATEVALUE(datetext)
Example: If you have a text string like "2024-08-16", using DATEVALUE("2024-08-16") converts this text into a date value that DAX can recognize and work with. This is handy when your dates are stored as text and you need to perform date calculations.
3) DATEDIFF Function:
Purpose: To calculate the difference between two dates.
Syntax: DATEDIFF(startdate, enddate, interval)
Intervals can be in years, months, days, hours, minutes, or seconds.
Example: DATEDIFF(DATE(2024, 1, 1), DATE(2024, 8, 16), DAY) would calculate the number of days between January 1, 2024, and August 16, 2024. If you use MONTH instead of DAY, it will give you the number of months between those two dates.
