Can contacts re-enroll into the workflow while using the date-field trigger?

Yes contacts can re-enroll into your workflows.
Click the Settings icon on top of your canvas and enable the re-enrolment of contacts option and select date-field trigger.

However, no contacts can re-enroll into a workflow twice on the same day when you've used the date-field trigger in your workflow.
Scenario: Say you've triggered a workflow on a specific date, 25.12.2021, and contacts have re-enrolled into the workflow on that date. You then change the date to 26.12.2021 and set exit criteria for which certain contacts would have exited the workflow. Now you change the date back to 25.12.2021, the contacts who have exited the workflow will not be allowed to re-enter into the workflow on the same date again.
