Winter occurs as the Earth's axis tilts away from the sun during the planet's annual rotation. The portion of the Earth that is furthest from the sun experiences winter, with weather that is colder than the other seasons. In the Northern Hemisphere, winter officially begins with the winter solstice, around 21 December, and ends at the spring equinox, around 21 March. Winter figures largely in Canada's climate, cultural experience and mythology. Every aspect of life in Canada is affected by winter, whether by heavy rains on the West Coast, isolation during the long Arctic winters, raging blizzards across the prairies or huge snowfalls in eastern Canada. Winter is reflected in Canadian art, literature, music, fashion, pastimes and attitudes.
