Winter Solstice and DST

Today is the Winter Solstice in the Northern Hemisphere. Most people supposedly know the Winter Solstice marks the shortest day of the year with relevance to daylight hours. Most people supposedly know; however, six weeks ago when we returned to Standard Time (normal time), many of those people who supposedly know where complaining that it was dark because DST ended. The assumption they made is wrong. It was dark because we were already advancing towards today, Winter Solstice. A day on planet Earth lasts 24 hours regardless of DST or Standard Time (normal time). During winter daylight is less than in the summer. Who doesn't know this fact? DST must be confusing many, and I wouldn't doubt the daily hour of unhealthy sleep deprivation is to blame. What a waste of time! Abolish DST!
