That depends on the meaning.
One meaning is longest daylight hours. This happens at summer solstice.
Another meaning is, the time the earth takes to spin on its axis once, with reference to the sun. This happens at perihelion of earth's orbit, where it is more than 24 clock hours.

What is the longest day in canada in 2008?
The longest day in Canada in 2008 was June 20th, which is the summer solstice. This is when the Northern Hemisphere experiences the longest period of daylight in the year.
Are the longest days always in the summer?
No, not necessarily. It is the longest day and it is when the solar declination is greatest, however that does not necessarily make it the hottest day. The hottest time of year is typically a month or two after the solstice after the land, and especially water, has heated enough to heat the air above it the most.
What December day has the longest sunlight?
The December day with the longest sunlight usually occurs around December 21st, which is known as the winter solstice. This is when the Northern Hemisphere is tilted farthest from the sun, resulting in the shortest day and longest night of the year.
What is the name of the longest day of the year and the beginning of summer?
The longest day of the year is called the summer solstice. It marks the official beginning of summer in the Northern Hemisphere.
Which state in the US has the longest and shortest day of the year?
Alaska has the longest day of the year with almost 24 hours of daylight during the summer solstice. Hawaii has the shortest day of the year with around 10 hours of daylight during the winter solstice.
Which outer planet has the longest day?
Uranus has the longest day of any planet in the solar system, with a rotation period of about 17 hours and 14 minutes.
What planet has the second shortest day?
Mercury has the 2nd longest "sidereal day" with a sidereal rotation period of 58.646 Earth days. The longest "sidereal day" day is Venus, with a sidereal rotation period of 243.018 Earth daysIf you use the "solar day" as your definition of "day", the order is reversed. Mercury then has the longest day and Venus has the second longest day.
Which is the longest solar eclipse?
The longest solar eclipse is about 7 minutes 40 seconds.
Which is longer the stellar day the sidereal day or the solar day?
Usually the solar day is the longest. The other two are very similar in length to each other. For example, the solar day on Earth is about 4 minutes longer than the other two "days". However, for the planet Venus the solar day is the shortest. That's because Venus has retrograde rotation.
Which planet has the longest day sunrise to sunrise?
Venus has the longest sidereal day (period of rotation or spin). This "day" is 243.0185 Earth days long and Venus rotates in the opposite direction of Earth. This day on Venus is actually longer than its "year". It takes more time for the planet to turn one time on its axis than it takes to go around the Sun. A "year" on Venus takes only 224.7 Earth days.However, the longest solar day occurs on Mercury, which completes its slow spin about once every 59 Earth days but also circles the Sun in just 88 Earth days. This tidally-locked combination leads to a solar day (roughly sunrise to sunrise) of 176 Earth days, twice as long as the "year".On Venus, because it rotates clockwise but orbits counter-clockwise, the effect is to make a solar day ("daytime" is brighter, but there's no sunrise through the clouds) about 116.75 Earth days.Minor comment: The actual question may be asking something different, but that's not clear.
What planet in your solar system has the longest day?
Venus, its day is equivalent to 243 Earth Days. That's the rotation period, or "sidereal day". However the "solar day" on Venus is only about 117 Earth days. If you mean the "solar day" then Mercury has the longest day because Mercury has a solar day of about 176 Earth days.
Is the solar day longest in July or January?
The solar day is actually the same length in July and January. A solar day is defined as the time it takes for a specific point on the Earth to rotate back to the same position relative to the Sun, and this does not change based on the month.
The planet with the longest day is?
Mercury has the longest "solar "or apparent day. Mercury takes 88 Earth days to go around the Sun, so its year is 88 Earth days. It spins very slowly on its axis though, once every 58.6 Earth days days relative to background stars. A solar (apparent) day on Mercury takes 176 Earth days, because of this slow spin relative to the time taken to orbit.The spin of Venus relative to the background stars is slower, taking 243 Earth days to spin once on its axis. But since its spin is retrograde (clockwise as viewed from above the north pole) and in the opposite direction of orbit around the sun, the apparent solar day is less, at 116.75 days.So, Mercury has the longest "Solar day". However Venus has the longest "sidereal day", because that's defined as the rotation period.
What is the name of the planet with the longest day compared to an earth day?
Venus. The length of "day" is 243 Earth days. That's the rotation period which is called a "sidereal day". However, there's also a "day" called the "solar day". That's the time for the Sun to complete one apparent journey around the sky. For that definition of "day", it is Mercury that has the longest day at about 176 Earth days.
Which planet has the longest cycle of day and night?
The planet is Mercury. (Some people think it is Venus, but it is Mercury.)
What planet has the longest day sunrise to sunrise?
The answer is NOT Venus. It is MERCURY. Venus takes longer to spin once than does Mercury. However Venus spins in the opposite direction to Mercury. The result is that Mercury has the longest "sunrise to sunrise" times.
When was Longest Day created?
Longest Day was created in 1998.
