Binary Time

We are very much used to our sexagesimal numeral system to measure time. In this base 60 system a day has 24 hours, each hour has 60 minutes and each minute is divided in 60 seconds. A more logical method of time keeping would be a decimal system (base 10 system) dividing a day in 10 hours, with 100 minutes per hour, and 100 seconds in each minute. But we live in a computer age and since all our information is stored in a binary form (in bits), we should perhaps consider switching to binary clocks.

In a decimal numeric system we use 10 different digits (0 to 9), but a binary numeral system represents numeric values using only two symbols (0 and 1). Here is a table showing how decimal values are represented in a binary way:

Decimal Binary Explanations for
0 0 Naught
1 1 One one
2 10 One two and zero ones
3 11 One two and one one
4 100 One four, zero twos and zero ones
5 101 One four, zero twos and one one
6 110 One four, one two and zero ones
7 111 One four, one two and one one
8 1000 One eight
9 1001 One eight and one one
10 1010 One eight and one two
11 1011
12 1100
13 1101 etcetera
14 1110 and so on
15 1111 and so forth
16 10000  

The binary clock on this page is in fact a sexagesimal clock shown in a binary format. Perhaps your next birthday present is a binary watch.
