The term “relief date” in the context of convicts usually refers to the date on which prisoners are released from prison or the date when their sentence is significantly altered in a way that relieves them from their current penal conditions.

This could be due to different reasons, including…

• Parole
• Completion of their sentence
• Commutation of their sentence
• Other legal actions that result in their release or a reduction in the severity of their confinement

The specific meaning can depend on the legal system or jurisdiction in question. Still, generally, it marks a point in time when the individual’s status changes in a manner that lessens their penal burdens.
