If you were born on Groundhog Day, your zodiac sign is Aquarius. Aquarius is the eleventh astrological sign in the Zodiac, originating from the constellation Aquarius. People born in between January 20th and February 18th are said to be under the sign of Aquarius. People born under Aquarius are known for their strong beliefs and independent nature. They are also known for being progressive and having a great sense of humor. People born under this sign are often seen as eccentric and have a unique view of the world. Groundhog Day falls on February 2nd, so if you were born on this day, you are an Aquarius.

Last I checked with my groundhog he didn't have any superstitions, however, humans who live predominantly in North America have a weather forecasting superstition (or more precisely a myth) about him.

It is believed that the groundhog always comes out of his den on the second of February to ascertain the weather conditions.

If when he pokes his head out of hi den, he sees his shadow (the day is bright & sunny) then it is said he returns to his den because winter has six more weeks of control of the land.

If he does not see his shadow (the day is overcast or the weather inclement) he remains above ground and expects Spring to appear.

This can most likely be traced back to an old British rhyme:

If Candlemas be fair and bright,

Come, Winter, have another flight.

If Candlemas brings clouds and rain,

Go Winter, and come not again.

Groundhog day is celebrated on the same calendar day as the religious holiday of candlemas was.

A cloudy winter day is warmer than a sunny winter day because the clouds reflect the heat radiating from the earths surface and traps them in the atmosphere. On a sunny (cloudless day) the heat radiates out into space and is lost.

on cloudy day the sun rays can't reach the earth surface for evaporation of water which causes cooling, moerover atmosphere is saturated of vapours so evaporation is very less from earth surface as compare to that of sunny day
