The date-based trigger can be set to check daily, weekdays, or weekends at any specific hour in the contact's timezone or the account timezone.
To schedule an automation at a fixed date and time or on a recurring schedule, learn about the "On a Schedule" trigger.
The Date Based Trigger functions as if it were "Runs: Once." Meaning if a user changes the time the Date Trigger checks to a later time, any contacts who have already triggered the automation that day will not trigger it again.
