The winter solstice (aka December solstice) happens every year when the Sun reaches its most southerly declination of -23.5 degrees - this is the same for everyone in the world no matter where you live.
The Met Department has confirmed that the sun will rise at 6:59 am and will set at 5:04 pm, shortening the day to 10 hours. The days would now start lengthening till June 20 to June 21 when again the process would repeat itself.
The rays of the sun become perpendicular to the Tropic of Cancer at 23°30 North latitude on June 21. This day is the summer solstice in the Northern Hemisphere.
