This annual time adjustment continues to be a point of debate. While proponents argue for energy savings and increased evening leisure time during DST, critics point to disruptions to sleep schedules and potential health consequences. The fact that several states and territories opt-out highlights the lack of global agreement on its benefits. Expect continued discussion about potentially adopting permanent DST or Standard Time nationwide.
