December 21 marks one of the turning-points of the year. The days seem more or less equal; the closer you are to the equator, the more true that is. For the northern hemisphere, we have our shortest night and we get a smidgen more light every night until the third week in June. In the southern hemisphere, it’s the exact opposite: the days get shorter and the nights longer.
The winter solstice is today, 21 December. The winter solstice is where the Earth is furthest from the sun in its angled cycle and then starts moving towards the highest point. The word “solstice” means “stillness” because, for the split-second of the solstice moment, the Earth appears to hold still.
