Challenge your brain. Binary Clock 24 is a free app that displays time using a binary system.
The Binary Clock 24 iOS app was designed to:
There are 3 rows of white and/or black circles. The top row are the hours (24 hour format), the middle row are the minutes and the bottom row the seconds.
A binary number can only have 2 states, such as on or off, true or false, yes or no. In the app, the on state is a filled white circle and the off state is a black circle with a white outline.
From left to right, the white circles in a row represent the numbers 32, 16, 8, 4, 2 and 1. To read the time, add all the white circle numbers in a row. Black circles represent the number 0.
If only the 2 and 1 white circles are on in the first row, the time would be:
If only the 32, 8 and 2 white circles are on in the middle row, then the time would be:
If there are no white circles on in the bottom row, the time would be 0 seconds.
The following is a table with some 12 hour clock conversions to a 24 hour format (also known as military time).
|12 Hour Clock||24 Hour Military Time|
Note that the first row (the hours) does not have a circle representing the number 32. It’s not required since there are only 24 hours in a day.
Tap anywhere on the clock then tap on the help button to access this page. Tap an empty area to return to the clock.
