What are heavenly stems?

Heavenly stems are like numbered labels that help us count and name things in a special way.

Imagine you have 10 different colored blocks, red, blue, green, yellow, purple, orange, pink, brown, gray, and white. Each color is a heavenly stem, and they go from 1 to 10. These labels help people in some cultures keep track of time or events.

Think of them like numbered tags you put on your toys, one tag for each toy. If you have five toys, you label them 1 through 5. In the same way, heavenly stems are used to count years or days in a cycle of 10.

Just like how you might use numbers to keep track of your favorite games or snacks, people who use heavenly stems use them to mark important dates or patterns in their lives, kind of like having a special calendar that repeats every 10 days or years.
