Its called an equinox. There is the Spring and the Autumnal Equinox. This occurs when the Sun is directly above the equator. It means equal day, where the days and nights are of the same length. See the related link for more information.
A period of time when the day time hours are equal to the number of night time hours is called an equinox. This occurs twice a year, in spring and autumn, when the Earth's axis is tilted neither toward nor away from the sun.
The astronomical event you are referring to is known as an equinox. It occurs twice a year, around March 20th and September 22nd, when the Earth's axis is not tilted towards or away from the Sun, resulting in nearly equal lengths of day and night worldwide.
The Sun reaches an EQUINOX when it is directly above Earth's equator and the number of daylight hours equals the number of nighttime hours all over the world. At this time, neither the northern or the southern hemisphere is tilted toward the Sun.
Your birthday occurs more often than a lunar eclipse. Lunar eclipses happen roughly twice a year, whereas your birthday occurs once a year.
Dan's mass is the same as it is on Earth. His weight, however, is doubled.
When neither hemisphere is tilted toward the sun, it is known as an equinox. During an equinox, there is nearly equal amounts of daylight and darkness all across the world. This phenomenon occurs twice a year, in March and September.
occurs twice per year, sun is direct at the equator and neither hemisphere is pointed toward or away from the sun....... ( around March 21 and around September 23) * means EQUAL Day and Night* Spring and Fall*
A period of time when the day time hours are equal to the number of night time hours is called an equinox. This occurs twice a year, in spring and autumn, when the Earth's axis is tilted neither toward nor away from the sun.

The letter "O" occurs twice in the word "October," once in "November," but not at all in "September."
It spins on an axis that is tilted with respect to the plane of its orbit around the Sun. This tilt means that first one pole, then the other, is tipped toward the Sun as the planet circles the Sun. When the North Pole is inclined toward the Sun, it is summer in the Northern Hemisphere and winter in the Southern Hemisphere. When the South Pole is inclined toward the Sun, the Southern Hemisphere has summer and the northern has winter. Twice a year (spring and fall equinoxes) neither pole is tipped toward the Sun for a brief moment. On that day, day and night are about equally long (12 hours) for the entire planet. The axial tilt is about 23.5 degrees to the perpendicular to the orbital plane.
It occurs when it is a SPRING TIDE. It occurs twice a month.
The letter "u" occurs twice in August, once in June, but never in September.

There are 12 factorial or 479,001,600 permutations of the letters in the word SOCIOLOGICAL. However, since the letter O occurs three times, the letter I occurs twice, the letter L occurs twice, and the letter C occurs twice, you have to divide that by 8 (O), 2 (I), 2 (L), and 2 (C) giving you 7,484,400 distinctpermutations.
