What is numbers on a clock?

A clock face typically has 12 numbers, representing the hours of the day. The numbers are arranged in a circle, with each hour marked by a different number. The numbers on a clock are usually in Arabic numerals, but some clocks may use Roman numerals instead. The numbers are evenly spaced around the circumference of the clock face, with each hour separated by 30 degrees of angle. Additionally, some clocks may have smaller numbers or marks between the hour markers to indicate minutes or seconds. In traditional clock design, the numbers on the clock face are usually presented in two sets of six, with the numerals printed in alternating colors or alternating font styles to aid in reading the time more easily.
