The Shortest Day of the Year
Today is December 21. Often in the northern hemisphere the day is called the shortest day of the year.
Many people interpret the phrase to mean the winter solstice and the number of daylight hours are the fewest of any day of the year.
Yet the phrase is technically incorrect. All days have the same duration. A strict reading of the phrase means a day with less than 24 hours.
These are the kinds of conundrums that technical writers endure.
