Winter is the phase of year when countries in the northern and southern hemispheres, respectively, see the least amount of direct sunlight.
December, January, and February in the Northern Hemisphere and June, July, and August in the Southern Hemisphere are the months when a portion of the Earth experiences the least amount of daylight. The Earth's 23.5° axial tilt as it orbits the sun causes solitons and varying solar declinations. This indicates that, during the year, one of the hemispheres is tilted toward the sun and receives the most intense solar rays, while the other receives the least amount of sunlight.
