Can I still use my Thailand Pass if my arrival date has changed?

A user has received their Thailand Pass but is concerned about using it since their arrival date was meant to be today. They are unsure if they need to reapply because of the change in their hotel booking. Community members respond, indicating that reapplication may be necessary if the arrival date changes. Additionally, there's confusion about a potential 72-hour window associated with the Thailand Pass, with some suggesting it applies to flight delays while others clarify that the date on the pass is fixed.
