No more sunsets before 5 p.m.? How permanent daylight saving would change winter

Proposed adjustments to the national timekeeping system could extend winter daylight hours, potentially allowing sunsets to occur after 7 p.m. during the coldest months. The concept has gained traction among policymakers and time zone experts who argue that modifying the current daylight saving schedule could better align clock time with natural light patterns. If enacted, the change would represent a substantial shift from the traditional twice-yearly clock adjustments that have governed U.S. timekeeping for decades.

Under the most frequently discussed framework, permanent daylight saving time would eliminate the annual fall transition back to standard time, effectively preserving later sunset hours throughout the winter season. Proponents point to research suggesting potential reductions in traffic collisions, modest energy savings, and expanded opportunities for evening commerce and recreation. Conversely, critics note that the adjustment would shorten
