What season has the longest day of the year?

Answer 1

It is the summer solstice, which normally occurs on 21st June. However in 2008 the exact solstice will occur at 23:59 hours on 20th June. In fact this is the first time since 1975 that it hasn't occurred on 21st June (it was 22nd June then)
In the Southern Hemisphere December 21st, in the northern June 21st

Answer 2

All days are the same length ... 24 hours ... everywhere on Earth. When the clocks move back, there is an extra hour in a day, making it 25 hours, so it can be argued that it is the longest day. That date varies in different countries each year as not all countries adjust their clocks on the same day and some don't do it at all.

If you're actually talking about the longest period of daylight in the year,

then it completely depends on where on Earth you're talking about.

At the south pole:

The sun never sets from September 21 to March 21.

Between the south pole and the Antarctic Circle:

The longest period of continuous daylight is between 24 hours and six months long,

depending on how far south you are. The center of it is December 21.

Between the Antarctic Circle and the Tropic of Capricorn:

The longest daylight is on December 21.

Between the Tropic of Capricorn and the Equator:

There are two longest periods of daylight in the year. They're both on days between

September 21 and March 21, and December 21 is midway between them.

On the Equator:

There are two longest periods of daylight in the year ... on March 21 and September 21.

Between the Equator and the Tropic of Cancer:

There are two longest periods of daylight in the year. They're both on days between

March 21 and September 21, and June 21 is midway between them.

Between the Tropic of Cancer and the Arctic Circle:

The longest period of daylight is on June 21.

Between the Arctic Circle and the north pole:

The longest period of continuous daylight is between 24 hours and six months long,

depending on how far north you are. The center of it is June 21.

At the north pole:

The sun never sets from March 21 to September 21.

First paragraph, right at the top: altering the clock does NOT change the number of hours in a day (it's still 24), not does it alter the length of daylight. Putting the clocks back or forwards simply re-times our behaviour to match slightly more closely the available daylight; and for most people this is more useful in Summer than in Winter.
