Although the summer solstice is the longest day of the year for that hemisphere, the dates of earliest sunrise and latest sunset vary by a few days. [8] This is because Earth orbits the Sun in an ellipse, and its orbital speed varies slightly during the year.

Developed in Hellenistic astrology, it has possible roots in older Babylonian astrology, and it is the origin of the names of the days of the week as used in English and numerous other languages.
Given the different Sun incidence in different positions in the orbit, it is necessary to define a standard point of the orbit of the planet, to define the planet position in the orbit at each moment of the year w.r.t such point; this point is called with several names: vernal equinox, spring equinox, March equinox, all equivalent, and named considering northern hemisphere seasons.
Winter solstice is the shortest day of year, longest night of the year and the official first day of winter in the Northern Hemisphere. Find out about the science and traditions behind the solstice.
