Explanation
The vernal equinox, two moments in a year when the Sun is exactly above the Equator and day and night are of equal length; also, either of the two points in the sky where the ecliptic (the Sun’s annual pathway) and the celestial equator intersect.
In the Northern Hemisphere the vernal equinox falls about March 20 or 21, as the Sun crosses the celestial equator going north.
In the Southern Hemisphere, the equinox occurs on September 22 or 23, when the Sun moves south across the celestial equator.
The midnight sun is a natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle when the Sun remains visible at the local midnight.
Around the summer solstice (approximately 21 June in the Northern Hemisphere and 23 December in the Southern Hemisphere), the Sun does not set below the horizon within a 24 hour period.
The countries and territories whose populations experience the midnight sun are limited to those crossed by the Arctic Circle: The Canadian Yukon, Nunavut, and Northwest Territories; the nations of Iceland, Finland, Norway, Sweden, Denmark (Greenland), Russia; and the State of Alaska in the United States
