What happens if daylight savings was permanent?
Permanent daylight saving time would keep the sun up later in the day, but would also mean the sun rises later. In the winter months that could mean some places won’t see sunlight until as late as 9 a.m. Permanent standard time would end there still being daylight at 9 p.m. in heart of summer in Berks.

What country is the most ahead in time?
