Binary Clock & Time Converter
See the current time in binary or convert any time to binary format. This live binary clock displays hours, minutes, and seconds as bits. A fun tool for learning and novelty.

Binary Clock
A binary clock displays time using binary numbers. Each column represents hours, minutes, or seconds in binary format. Lit bits (1) represent active powers of 2.
Hours use 5 bits (0-23), while minutes and seconds use 6 bits each (0-59).
How It Works
This binary clock and time converter displays the current time in binary format and converts between standard time (HH:MM:SS) and binary representation. It's both a functional tool and a fun way to understand binary numbers.
The conversion process:
- Get current time: Hours, minutes, and seconds are extracted from the system clock.
- Convert each component: Hours (0-23), minutes (0-59), seconds (0-59) each convert to binary separately.
- Display as bits: Each time component shows as 6 bits (enough for max 59), often in columns.
- Live updates: The display updates every second to show the changing binary time.
For example: 14:35:27 in binary is 001110:100011:011011. Binary clocks typically display this as vertical columns of LED-like bits that light up for 1s.
When You'd Actually Use This
Learning Binary Numbers
Practice reading binary in a fun, practical context with constantly changing values.
Binary Clock Enthusiasm
Read your actual binary clock by understanding how the time is encoded in bits.
Teaching Time Representation
Show students different ways to represent the same information (decimal vs binary).
Programming Projects
Build your own binary clock application or widget using this as a reference.
Novelty and Fun
Impress friends by reading binary time, or use as a conversation-starting screensaver.
Digital Electronics Learning
Understand how digital clocks internally represent and display time values.
What to Know Before Using
Hours use 5 bits (0-23)
2^5 = 32 values, enough for 0-23. Some displays use 6 bits for consistency with minutes/seconds.
Minutes and seconds use 6 bits
2^6 = 64 values, enough for 0-59. The top values (60-63) are unused in timekeeping.
Binary clocks have different modes
BCD mode shows each decimal digit separately. Binary mode shows the full value. This tool uses binary mode.
12-hour vs 24-hour format
24-hour format (0-23) is more common for binary clocks. 12-hour needs an extra AM/PM indicator.
Reading takes practice
At first, you'll need to calculate. With practice, common times become recognizable patterns.
Common Questions
How do I read a binary clock?
Each column represents hours, minutes, or seconds. Read bits from bottom to top (1, 2, 4, 8, 16, 32). Add up the values of lit bits.
What's 14:35:27 in binary?
Hours: 14 = 001110 (8+4+2). Minutes: 35 = 100011 (32+2+1). Seconds: 27 = 011011 (16+8+2+1).
Why do binary clocks use columns?
It mimics how digital displays show digits side by side. Each column is independent, making it easier to read.
What's BCD mode on binary clocks?
Binary Coded Decimal represents each decimal digit separately. 14:35 becomes 0001 0100 : 0011 0101 (each digit is 4 bits).
Can I convert any time to binary?
Yes! Any valid time (00:00:00 to 23:59:59) converts to binary. Just convert each component separately.
Are there binary clock apps?
Yes! Many smartphone apps, desktop widgets, and even physical binary clock kits exist. Some watches have binary clock modes.
What's the hardest part about reading binary time?
Speed. You can calculate any time, but reading at a glance takes practice. Common times (like 12:00) become recognizable patterns.
