Winter solstice 2015: All you need to know

Winter solstice is going viral across the world. There is no denying the fact that the whole world wants to celebrate winter solstice or the first day of winter in great style.

Most of the people were thinking that winter solstice will be on December 22. But was it really the case?

A report while talking about it says, “The whole world marks the solstice at the same time, and this year that time was 4:49 a.m. Universal Time on Dec. 22. Pacific Standard Time is eight hours behind, so the solstice for us was 8:49 p.m. Monday….Winter solstice is most commonly on Dec. 21. The next most common date is Dec. 22, and it is sometimes (rarely) on Dec. 20 or Dec. 23.”

This year people were so much enthusiastic about the winter solstice that it was going viral on all the top social networking sites as well as on search engines.Dal Lake in Winter

By the way why is winter solstice such an important occasion but why no one actually talks about summer solstice? Winter To an astronomer, it’s when the Earth’s North Pole is tipped at its farthest point away from the sun — specifically, at a 23.5-degree angle.

Wikipedia while detailing it says, “The axial tilt of Earth and gyroscopic effects of its daily rotation mean that the two opposite points in the sky to which the Earth’s axis of rotation points (axial precession) change very slowly (making a complete circle approximately every 26,000 years). As the Earth follows its orbit around the Sun, the polar hemisphere that faced away from the Sun, experiencing winter, will, in half a year, face towards the Sun and experience summer. This is because the two hemispheres face opposite directions along Earth’s axis, and so as one polar hemisphere experiences winter, the other experiences summer”.

In simple language winter solstice is when the northern hemisphere has its shortest day of the year. In San Jose, there was 9 hours, 35 minutes and 21 seconds between sunrise and sunset on Monday. Today it will be less than a second longer.
