The shortest day falls on which date?

The shortest day falls on which date?

• A. 21 December
• B. 22 December
• C. 20 December
• D. 23 December

Answer: (A)

The shortest day occurs at the winter solstice, when the Sun reaches its lowest point in the sky due to the tilt of the Earth's axis. Because the year isn’t a perfect 365 days and the solar year interacts with the calendar, this solstice falls around December 21, sometimes shifting to December 22 in some years. That makes December 21 the most common date used for the shortest day.
