Mars.
24 hours.
Mars has a day of 24 hours 39 minutes and 35 seconds
Everywhere: the length of the day is always 24 hours irrespective of latitude & longitude since the angular rotation of the planet is 360º per 24hours. The DAYLIGHT length changes seasonally and proportionally to latitude, but the DAY length is constant.
The length of day alone does not provide enough information to determine latitude. The length of day varies with latitude, but other factors such as time of year and location also influence it. To find latitude, you typically need additional information like the altitude of the sun at noon or the angle of the shadows cast by objects.
The length of a day (one rotation of the earth) does not change by any significant amount. The amount of daylight received will vary according to your latitude due to the axial tilt if the earth and the earths position in its orbit around the sun
The tides are slowing the earths rotation and making the day longer.
The length of the day
The equator is defined as zero latitude.
The length of the day varies depending depending on latitude and season (Winter, Fall, etc.)
The length of day and night depend upon the season of the year and the latitude of the desert. Over a year it averages 12 hours of day and 12 hours of night.
If you mean the length of the day, yes - that is the same around the Earth. The Earth rotates as a rigid body. If by day length you mean hours of sunlight. On the same lines of latitude day length will be the same, but due to the wobble in the rotation of the earth, day length is different along lines of longitude.
