The term "Duodecimal" refers to a base-12 numeral system, which uses twelve distinct digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, and B. In this system, each place value represents a power of twelve, making it different from the more commonly used decimal (base-10) system. The duodecimal system can simplify certain calculations and is sometimes used in specific fields, such as mathematics and computing. Historically, various cultures have utilized duodecimal counting, including the ancient Babylonians and Mesoamericans. The system is also seen in modern applications, such as in measuring time (12 hours on a clock) and in the division of a year into months. Advocates of duodecimal argue that it offers advantages in fractions and divisibility compared to decimal.
