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 calendar vs relative key differences feature calendar date relative date based on fixed calendar periods current date (rolling window) dynamic? ❌ static ✅ dynamic example “in calendar month april 2025” “in previous 30 days” best for reporting, quarterly reviews, exports automations, lifecycle campaigns changes over time? no, unless updated manually yes, updates every time it runs https //support deselect com/hc/en us/articles/360005239378 filter types in deselect segment
