∙ 12y agoThe usual answer is at the March (vernal equinox) and September (autumnal equinox). However this is not really true. Do to effects like refraction, the sun seams to rise earlier and set later than simple geometry would dictate. Thus if you check any almanac, you will see that there are several minutes more of day than night on the equinox days. The actual day of equal day and night would be several days before the March equinox and after the September equinox. The exact day depending on your lattitude.

∙ 12y agoThe two days of the year that are of equal amounts of both day and night are the autumnal and vernal equinoxes. They usually fall around September and March 22. But they vary. As with the solstices in June and December, they signify the beginning of Spring and Autumn.

∙ 12y agoOn the vernal and autumnal equinoxes, the hours of day and night are about equal in every place in the world. These dates are on approximately September 23rd and March 21st so during Spring and Fall. Since the Sun's direct rays hit the Earth's equator on these days, the length of hours that every place in the world receives as day and night are equal because the equator is at the center of Earth's longitude lines. I hope this answers your question.

∙ 12y agoDays and nights are only of equal duration twice per year. It occurs on the summer solstice and the winter solstice.
The summer solstice occurs around June 20, it can vary from year to year. It signals the start of summer.
The winter solstice occurs around December 20, and can also vary from year to year. It signals the start of winter.
There are two days in a year when day and night are approximately equal in duration - the spring equinox and the autumn equinox. These occur around March 20-21 and September 22-23 respectively.

Twice, at the Summer and Winter Solstaces.
There are two days each year when the day and night are of equal duration, known as the equinoxes. The vernal (spring) equinox occurs around March 21st, marking the beginning of spring in the Northern Hemisphere, while the autumnal equinox occurs around September 22nd, marking the beginning of autumn.
One day on the moon is equal to approximately 29.5 Earth days. This is because it takes the moon about 29.5 days to complete one full rotation on its axis, which is the same amount of time it takes to complete one orbit around the Earth.
Divide the answer by 365 because it is number of days in a year. 2,920 / 365 = 8 Years.
After 4 days, only 1/16 of the original amount of gold (198/16 = 12.375) will remain.
Two times

There are two days of equal length- they are called the equinoxes. And to the person below who asked a question by writing in the ANSWER space- shadows of the sun appear to move because the Earth is rotating (turning)
3 Twice. On the Autumnal equinox and on the Vernal equinox.
8 days are equal to 11520 minutes.
There are two days each year when the day and night are of equal duration, known as the equinoxes. The vernal (spring) equinox occurs around March 21st, marking the beginning of spring in the Northern Hemisphere, while the autumnal equinox occurs around September 22nd, marking the beginning of autumn.
Two days equal 48 hours.
144 hours is equal to 6 (six) days.
14 days (2 weeks)
There are 24 hours in a day/night. Therefore 1 1/4th is equal to 1 day and 6 hours or 24 + 6 = 30 hours.
The Equinox (Vernal & Autumnal) There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a "nearly" equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes
101.64 days, of course!
