The clock shows the time for $$24$$ hours using only $$12$$ numbers, $$1$$, $$2$$, $$3$$,..., $$11$$ and $$12$$. After $$12$$, we use $$1$$ again for $$13$$ hours, $$2$$ for $$14$$ hours and so on. Here, the numbers are wrapped again from $$1$$ to $$12$$ to represent $$13$$ to $$24$$ hours. This way of again wrapping the numbers after a certain value is called modular arithmetic.
