<|im_start|>assistant
A day on mars is called a Sol whose name is borrowed from the Latin word for Sun. Compared to a day on Earth, a sol is slightly longer at 24 hours, 39 minutes, and 35 seconds which is equivalent to 1.0275 Earth days. Spacecraft that have landed on Mars conventionally use a 24 hour Mars clock where the hours, minutes, and seconds are 2.75% longer than the standard Earth durations.<|im_end|>
