What else can I help you with?
How many times a year do equinoxes occur?
There are two equinoxes (i.e. vernal/spring and autumnal/fall) every year.
How many days of the year does the equator have a 90 degree sun angle?
Two: the spring and autumn equinoxes.
How many times in a year day and night are of equal duration anywhere on earth?
That happens twice, at the "equinoxes".
Which two eqinoxes in the month?
There are two equinoxes per year, separated by about 6 months. There will never be two equinoxes in one month.
What are the difference between the equinoxes and the solstices?
The equinoxes and solstices are the first days of seasons. On the equinoxes, night and day is the same length. On the solstices, the day is either the longest or the shortest day of the year, depending on which solstice it is and which hemisphere you are in,
Why are the equinoxes special times during the year?
The year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses the Earth's equator.The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.
Does the leap day affect when equinoxes and solstices occur?
Yes. If we did not insert the leap day during leap year, the calendar date of the equinoxes and solstices would change and eventually come at very different times in the calendar year. The whole purpose of Leap Year/Leap Day is to keep our calendar aligned with the equinoxes, solstices, and seasons in general.
How many equinoxes are there in 1 year?
There are two equinoxes in a year: the vernal equinox, which occurs around March 20 or 21, and the autumnal equinox, which takes place around September 22 or 23. During these events, day and night are approximately equal in length due to the Sun's position relative to the Earth.
Is the sun closer to the equator during the equinoxes?
Yes, during the equinoxes, the sun is directly above the equator, making it closer to the equator compared to other times of the year.
What phenomena accounts for the 26000 year wobble which shifts poles and equinoxes?
precession
1st equalest day of the year?
The equinoxes are the two dates each year when the day and the night are of equal length.
What is significant about equinoxes?
The year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses the Earth's equator.The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.
