The year 2000, according to Kibo's HappyWeb Manifesto:
HappyWeb has the perfect solution to the Y2K problem!
The year after '99 will be referred to as "2K". Two digits, no fuss, no muss!
Subsequent years will also have unique two-digit names:
1999 -- 99
2000 -- 2K
2001 -- 2L
2002 -- 2M
...
2015 -- 2Z
2016 -- 30
2017 -- 31
2018 -- 32
...
With this intelligent use of letters and numbers we'll never run out of dates in a million billion trillion years!
It's also incidentally, how I notate the year 2000 in writing. I want to see people become confused when it becomes 2L. |
