The apparent solar day is longer in January due to the tilt of the Earth's axis and its elliptical orbit around the Sun. During this time, the Earth moves more slowly in its orbit, which affects the Sun's position in the sky. As a result, the time from one solar noon to the next is slightly extended, leading to longer apparent solar days. This phenomenon is part of the equation of time, which accounts for variations in the solar day throughout the year.
a solar day
Mars has a similar day length to Earth, a little longer at 24h 39m 35s (apparent solar day).
Its to do with the time taken for the planet to rotate once on it axis, Mars just takes a little longer, making its apparent day longer.
The solar day (or sol) on Mars is only slightly longer than an Earth day: 24 hours, 39 minutes, and 35.244 seconds.
Venus "sidereal day" is longer than its year. Mercury's "solar day" is longer than its year. However, there is no planet in our solar system with a day longer than our year on Earth.

Mars. It has a similar day length to Earth, a little longer at 24h 39m 35s (apparent solar day).

Almost. Mars has a similar day length to Earth, a little longer at 24h 39m 35s (apparent solar day).
An apparent or solar day on mars is 24h 39min and 35sec, so a night on mars will be 12h 19min and 47sec on average. A bit longer than on earth.
Apparent solar time is determined by the position of the Sun in the sky, taking into account Earth's rotation and its elliptical orbit around the Sun. It is based on the Sun reaching its highest point in the sky at 12 noon, varying slightly throughout the year due to Earth's tilt and orbit.
Because, when using "apparent solar time", the length of a "solar day" varies slightly during the year. (This is because the Earth's orbit isn't exactly circular and the Earth's axis is tilted.) "Clock time" is based on an average (or "mean") of these day lengths, called the "mean solar day". So clocks use "mean solar time". (By coincidence, on the date the question was answered (14th April) "apparent solar time" and 'clock' time are synchronised.) There's another reason for apparent solar time being different from clock time. "Clock time" uses time zones. So, over a wide area, the time on a clock equals the "mean solar time" at a particular, defining, longitude.
Apparent solar time
Time is based on the average length of the apparent solar day, which is the time it takes for the Sun to return to the same position in the sky, as observed on Earth. This forms the basis for the 24-hour day cycle that we use to structure our activities.
Mercury's solar day is about 176 Earth days. That's the time taken by the Sun to complete one apparent trip round the sky.
