BinarySauce was created on January 1, 2011. That date can be written as 010111 which is binary for the decimal 23. Today, January 11, 2011, is another binary date which, depending on the locale, can be written as 011111 or 110111 which is 31 and 55 respectively.
The second binary date was yesterday but I failed to write about it because I was really busy. Yesterday’s date could be written in binary as 011011 or 100111. That’s 27 and 39 respectively.
The next ones will come a bit later. That would be the 1st, 10th and 11th of October and November. The last binary date of 2011 will be November 11 which is also the last binary date of the 21st century as the next one after that won’t be until the January 1, 2101.
