The winter solstice marks the shortest day of the year, when the sun is at its lowest point in the sky.
In Fairbanks, Alaska, it's possible for office workers without a window view to never see the sun during December — except for weekends.
As the month with the shortest days of the year, the sun rises and sets in December while most people sit at their desks.
That's why residents go all out to mark the winter solstice, when the days shift from losing sunlight to gaining sunlight. This year, the town even funded its own fireworks display through Kickstarter. (Fireworks are better enjoyed during the winter darkness than in July's bright summer nights.)
