Assuming you have two date columns named "Date1" and "Date2" in your table, and you want to calculate the difference between them in days:
DateDifferenceInDays = DATEDIFF('Table'[Date1], 'Table'[Date2], DAY)
Replace 'Table' with the actual name of your table containing the date columns.
2. If you need the result in months, you can replace DAY with MONTH:
DateDifferenceInMonths = DATEDIFF('Table'[Date1], 'Table'[Date2], MONTH)
3. If you want a simple numeric result that represents the difference in days between two dates without considering months or years, you can use the '-' operator directly:
DateDifferenceInDays = 'Table'[Date1] - 'Table'[Date2]
