What is Binary?

Binary is a number system that uses only two digits: 0 and 1. Unlike our normal decimal system (base 10), binary is base 2.

Each position represents a power of 2. A 1 means "include this value", a 0 means "skip this value".

How to Read Binary Time

Reading binary time is like adding up the "on" bits for each time unit:

Calculation: 16 + 4 + 1 = 21 hours

💡 Quick Tips

Start from the left (highest value)
Add up all the "lit up" (1) positions
Skip the "dark" (0) positions
The sum is your time value!

Common Time Examples
