Winter Twilight

Winter

Winter is the coldest and darkest season of the year in temperate and polar climates. It occurs after autumn and before spring, when the hemisphere is oriented away from the Sun as a result of the tilt of Earth's axis. Different cultures define different dates as the start of winter, and some use a definition based on weather.

Twilight

Twilight is daylight illumination produced by diffuse sky radiation when the Sun is below the horizon as sunlight from the upper atmosphere is scattered in a way that illuminates both the Earth's lower atmosphere and also the Earth's surface. Twilight also may be any period when this illumination occurs, including dawn and dusk.

winter

Noun

1. Traditionally the fourth of the four seasons, typically regarded as spanning either the period between the winter solstice to the spring equinox, or the months of December, January, and February in temperate and polar regions of the Northern Hemisphere and the months of June, July, and August in the Southern Hemisphere. It is the time when the sun is lowest in the sky, resulting in short days, and the time of year with the lowest atmospheric temperatures for the region.
2. The period of decay, old age, death, or the like.

Verb

1. To spend the winter (in a particular place).
2. To store something (for instance animals) somewhere over winter to protect it from cold.

Adjective
