How does calendar and relative filter works?

When filtering records based on dates, you’ll often choose between Calendar and Relative date filters. These two approaches serve different purposes, and selecting the right one ensures your segments remain accurate—whether for static reporting or dynamic automation.

Calendar

Calendar filters refer to fixed timeframes—such as “this month,” “last year,” or a specific date range on the calendar.

They are anchored to calendar periods and do not change dynamically once defined (unless the segment is refreshed with a new run date).

Relative

Relative filters are based on time relative to the current date (today). These are dynamic filters that update automatically based on when the segment is executed.
