You can use the Date Transform tool to extract parts of date columns - such as a weekday or year. It is particularly helpful in combinations with others tools. Such as a Filter to keep transactions from the current year or a Group By + Combine to merge datasets by Year/Month.
Note that our Syntax also supports date trunc calculations (same as Date Transform). See more in the Syntax section.
