Why Do We Count in Groups of Twelve?

We count in groups of twelve because it's easier to use a number that has many factors. Think about how we divide things: 12 can be split into 2, 3, 4, or 6 equal parts, that’s more than just 10, which only splits evenly by 2 and 5! That makes counting with 12 really handy for things like sharing food or telling time. People long ago used their fingers and toes to count (that's 10), but the ancient Babylonians used a base-12 system because it made math faster and more useful in daily life.
