As early as 2,500 years ago, about the Spring and Autumn Period (770-476 BC), Winter Solstice was determined by observing movements of the sun with a sundial. Being the earliest of the 24 seasonal division points, it falls on December 21 or 22 according to the Gregorian calendar.
In 2019, it falls on 22 December.
The Northern hemisphere on this day experiences the shortest daytime and longest nighttime. After the Winter Solstice, days will become longer.
Today, the Winter Solstice is loosely celebrated by consuming 'Tang Yuan', a sweet delicacy of rice dumplings to symbolize a year of harmony and abundance (or fullness) to come.
The significance is to observe this day as a good start to clean up one's act and plan ahead. Gather the family for warmth and a hearty meal.
It's a time to reflect, forgive and plan ahead.
Take it easy on this day, start on a happy note, make a resolution and yes, make a wish.
