Mercury - 4222.56 hours (175.94 Earth days)
Venus - 2802 hours (116.75 Earth days)
Mars - 24.659789 hours
Earth - 24 hours
Uranus - 17.239722 hours
Neptune - 16.11 hours
Saturn - 10.543333 hours
Jupiter - 9.9258333 hours
These are the "solar days" not the "sidereal days" (period of rotation).
The differences between these "days" are large for Mercury and Venus.

No planet in our Solar System has 248 days in a year.The closest are:-Venus 224 days - although Venus has a day which lasts 243 days.Earth 365 days
Weeks are sets of 7 days used solely for Earth. Other planets have years because a year is the time it takes to go around the sun once and days because a day is how long it takes to turn once, but they do not have special months or weeks. So there is no such thing as a Martian week.Weeks are sets of 7 days used solely for Earth.

Rotation of planets depends on their history of being hit by other planetoids ... thus it is entirely random.
The length of each planet's days are different because they rotate at different speeds. A day on Mercury is equal to 58.5 days on Earth. A day on Mars takes 24 hours and 39 minutes on Earth. A day on Venus is 243 Earth days and a day on Jupiter is equal to 9.9 Earth hours.

Mercury has the shortest year of any of the planets. It is only 88 days. Mercury's day takes 58.646 Earth days.
The length of each planet's days are different because they rotate at different speeds. A day on Mercury is equal to 58.5 days on Earth. A day on Mars takes 24 hours and 39 minutes on Earth. A day on Venus is 243 Earth days and a day on Jupiter is equal to 9.9 Earth hours.
This might be more apparent to speakers of languages other than English. There is a closer match in French, for example. It is not that planets are named after the days of the week. Both the days of the week and the planets are named after various deities that have been influential in human thought over the centuries.
Venus or Mercury, depending on the definition of "day" used. It takes Venus 243 Earth days to spin on its axis relative to the background stars (a "sidereal day"). It takes Venus 224.7 Earth days to orbit the Sun (its year). However, a "solar day" is only 116.75 Earth days long due to the combination of rotation time, orbit time and spin direction. (Venus spins in the other direction to Earth and most other planets.)Mercury has a "sidereal day" of about 58.6 Earth days and a year of about 88 Earth days.
It depends on the planet and how fast it's going. Also, planets further from the sun have a longer path to travel. for example: Mercury only takes 88 days because it has a shorter path than all the other planets. Earth takes 1 year.Here are all the orbital periods of the planets measured in Earth days and Earth years:Mercury: 87.97 days (0.2 years)Venus : 224.70 days (0.6 years)Earth: 365.26 days (1 year)Mars: 686.98 days (1.9 years)Jupiter: 4,332.82 days (11.9 years)Saturn: 10,755.70 days (29.5 years)Uranus: 30,687.15 days (84 years)Neptune: 60,190.03 days (164.8 years)
