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.
243 Earth days
The length of a day is primarily controlled by the rotation of the Earth on its axis. The Earth takes approximately 24 hours to complete one full rotation, which determines the length of a day. Variations in the Earth's rotation speed can result in minor changes in the length of a day.
The SAME? No. "ABOUT" the same? Well, close; a Mars day is a little less than 25 hours.
