Winter Wonderland

Christmas is fast approaching. Aside from the usual hustle and bustle, it can be noted that during this season the nights are getting colder and longer. Well not really longer but it seems so. I for one love this season. Hmm…all the love and gifts, who wouldn’t be.

Okay, so we have what we call seasons. According to Wikipedia, the seasons result from the Earth’s axis being tilted to its orbital plane; it deviates by an angle of approximately 23.5 degrees. Thus, at any given time during summer or winter, one part of the planet is more directly exposed to the rays of the Sun. This exposure alternates as the Earth revolves in its orbit. Therefore, at any given time, regardless of season, the northern (NH) and southern hemispheres (SH) experience opposite seasons.

Have you heard of Winter Solstice? It is the shortest day of the year, it occurs either on December 21 or 22, when NH is leaning farthest away from the sun. It is also called Midwinter. While the Summer Solstice occurs on June 21 or 22 thus called Midsummer.

Now you know when did this Midsummer Night’s Dream happened in Shakespeare’s play.
