Why is the first day of summer the longest and shortest day of the year?

Answer 1

It's not. It's the longest, but not the shortest. The shortest is the first day of winter. And technically, they're both the same length, about 24 hours, but first day of summer has the most daylight and first of winter has the least. I has to do with the earth's rotation on it's axis-- on the first of summer the hemisphere in question is closest to and tilted towards the sun, maximizing daylight. The first of winter it's still closest to, but tilted away from the sun, minimizing daylight

Answer 2

This makes no sense....how can it be the longest and shortest at the same time???

It is the LONGEST day of the year - only because it has the most daylight out of any other day of the year... this is the opposite on the southern hemisphere, where Spetember 21 is the longest "day". The entire idea of days, months, years, the very idea of time iteself is a man made phenomenon.
June 21 is the longest day in the northern hemisphere because of the 23.5* tilt of the earth's axis, combined with where the planet is in its elliptical path around the sun. The 23.5* angle is mostly static (it varies by as much as 2*, but this takes 12000+ years to "see".), so it is the area the planet travels through that makes days and night change in length... But, no matter what "day" it is, a "day" is always 23 hours, 56 minutes. A "year" is the time the earth takes to revolve around the sun - this is actually 365 1/4 days! this is why we have leap year every four years...to balance out our calendar system!

Answer 3

The first day of summer is the longest day of the year because somewhere, at some time, that is what someone decided. Same with the firs day of winter being the shortest day of the year. It makes sense and is consistent. If you said summer started when all the ice was melted off the lake or river, it would pretty much be a different day each year. Same with winter. If you said it was the day of the first snowfall it would be on different days. Especially for different regions, countries and latitudes.

Answer 4

The longest day of the year is on Summer`s solstice and the shortest is on Winter`s. (The first day of Summer and Winter in Persian calendar)
this happens as a result of the 23.5 degree angle between the axis of Earth and the normal vector of its path.
This results in the growth of the day as the earth passes the spring equinox and reaches the summer solstice and v.s
Also you should remember that being in north or south hemisphere plays an important role. all the above is for the north hemisphere and will be reverse for the south.

Answer 5

June 21 is the longest and December 21 is the shortest

Answer 6

If anyone were to call it the longest and shortest... Perhaps they are thinking of work, before and after you finish the day of work, you still have plenty of daytime? Making work seem like a shortday?

Answer 7

The summer soltice is the longest day of the year. Some designate that as the first day of summer, but others don't (for example, the Irish regard the summer soltice as "midsummer" and their first day of "summer" is in May).

Its long or short depending on which hemisphere you are on (Northern-long, Southern- short -- when its "summer" in the Northern hemisphere -- the opposite is true in "winter".

Answer 8

Coz u reversing the Day.
