What is the longest day for 50401?

The longest day of the year is the Summer Solstice, which normally happens on June 21 in the northern hemisphere and December 21 in the southern hemisphere. These dates can vary a day either way, depending on the cycle of leap years. Check the link below to see a list of solstices and equinoxes from the US Naval Observatory's web site "Earth's Seasons".


When are the solstices and the equinoxes?

Equinoxes are when there are twelve hours of daylight and 12 hours of darkness. The autumnal equinox is on September 21st on average, and the vernal equinox is on March 21st on average. You can tell that the seasons have changed and the equinoxes and solstices have occured because the amount of sunlight changes and temperatures also change. Solstices are when there is either the shortest or longest amount of daylight. The summer solstice is when there is the longest amount of daylight. After the summer solstice, days begin to slowly get shorter until the autumnal equinox. The winter solstice is when there is the shortest amount of daylight. After the winter solstice the days get longer until you reach the vernal equinox.


What are Similarities of summer solstice and winter solstice?

On the equinoxes day and night are of equal duration. On the solstices the difference between day and night are their maximum (longest day for summer solstice ... shortest day for winter).


What are the two equinoxes?

The two equinoxes occur every spring and autumn. The "equinoxes" are two points on the map of the stars. The center of the sun reaches and passes one of them at some moment around March 21, and the other one at some moment around September 22. At those moments, the sun is directly overhead some point on the earth's equator, and every place on earth has roughly equal periods of sun-up and sun-down on that day ... the only two times in the year when these things happen.

Are there different end dates for spring depending on the year?

Yes, the date of each of the equinoxes and each of the solstices varies from year to year due to the differences between a calendar year (365 or 366 days) and an average actual year (about 365.24219878 days). The dates of the solstices and equinoxes also vary depending on where you are on earth, since there are always at least two days in progress on earth at any given time.


What are some dates of the event of an solstice and an equinox?

The solstices are generally on June 21 and December 21; the equinoxes are usually on March 21 and September 21. These dates can vary a day or two either way, depending on the cycle of leap years. The U.S. Naval Observatory publishes a web page called "Earth's Seasons" which lists the dates and times of the solstices and equinoxes for each year, down to the minute. See the link below.

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.
