When filtering by a timestamp attribute, you can now refer to a specific recurring time period. For example, you can select first_session > weekday matches > equal to 1, which will only filter first session events that were tracked on Monday. You can also work with seconds, minute, hour, weekday, day, week, month, and year.
For example, you can filter the customers who have a purchase anniversary today and provide them with a special discount.
