The truth is...
A day is 24 hours long, plus or minus about 20-30 seconds. However, during the winter the days get longer. At the winter solstice the days are the shortest.
But the southern hemisphere is different. In the southern hemisphere the days are nearly always 24 hours (+/- about half a minute).
And on the equator it gets really weird, because a sidereal day on the equator is only about 23 hours, 56 minutes year-round. And at the north and south poles, occasional the day is a second longer (leap second), due to climate change, among other reasons.
In space, astronauts experience time differently because they are in an area of lower gravity due to general relativity. For example, the International Space Station experiences 16 sunrises and sunsets per Earth day.
In areas where there is daylight saving time, on the day those areas enter daylight saving time the day is 23 hours, and when it switches back to standard time it’s 25 hours. These short and long days only occur in the areas where there is daylight saving time which you’d think would cause massive geological strain on the Earth’s crust and upper mantle, but for some reason it doesn’t.

#TruthBeTold = A statement that is logically or literally true (or partly true), but seems to imply something that isn’t true or is just plain weird. (for rhetoric, logic or propaganda studies… or just for fun)
