   When do solstices occur?

   • Solstices occur twice yearly: once in winter (December 21-22) and once in summer (June 21-22). The result is longer days for those who live on the side facing the sun and shorter days for those who live on the side facing away from it. Solstices occur when Earth’s axis is tilted 23 degrees relative to its orbital plane around the Sun.

   May 22, 2024 · The equinox occurs when the sun crosses the celestial equator and marks the point where day and night are equal. In the Southern Hemisphere—that is, anywhere south of Earth’s equator—the September equinox happens in spring. In contrast, it occurs in autumn in the Northern Hemisphere.

   May 24, 2024 · Seasons are caused by the fact that the Earth is tilted on its axis by 23.5°. The tilt's orientation with respect to space does not change during the year; thus, the Northern Hemisphere is tilted toward the sun in June and away from the sun in December, as illustrated in the graphic below.

   May 31, 2024 · On Earth, an average night is shorter than daytime due to two factors. Firstly, the Sun’s apparent disk is not a point, but has an angular diameter. Secondly, the atmosphere refracts sunlight so that some of it reaches the ground even when the Sun is below the horizon.

   May 22, 2024 · Equinoxes and solstices are two of the most important celestial events on Earth. The equinoxes occur around March 20 and September 22 each year, corresponding to an equal length of day and night. The Earth tilts on its axis so that the sun shines directly over the equator on these days.
