Daylight Saving Time Ends Sunday: What You Need to Know

Daylight saving time ends this Sunday in the US, with clocks falling back an hour at 1 a.m., leading to earlier sunsets and darker evenings until spring. Most of the US observes this change, except Hawaii, most of Arizona, and US territories. The practice, established in 1918, aims to extend daylight hours in summer but has faced debates and legislative efforts to make daylight saving time permanent. Experts have mixed opinions on the health impacts of the time change.
