Question 1

What is a binary clock?

Accepted Answer

A binary clock displays the current time using binary numbers (base-2) instead of decimal. Each digit is represented by a column of LED dots, where lit dots represent 1s and unlit dots represent 0s, read from bottom to top.

Question 2

How do I read a binary clock?

Accepted Answer

Each column represents a time unit (hours, minutes, seconds). Read the lit dots from bottom to top: bottom=1, next=2, then 4, then 8. Add the values of all lit dots in a column to get the decimal number for that position.

Question 3

Does this binary clock show real time?

Accepted Answer

Yes. The clock uses your device's local time and updates every second. It shows hours (0-23), minutes (0-59), and seconds (0-59) in real-time binary format.

Question 4

Is the binary clock free to use?

Accepted Answer

Yes, completely free with no signup required. The clock runs entirely in your browser and works offline once loaded.
