So 1996 means 196?as I chop off the 19, the year 1000 is implied and then tack on the next two significant digits of the year which is 96 and leaves off the specific year. What? I have no idea what you mean by this.

It means:

  fakeyear = Math.floor((realyear - 1000) / 10) + 1900

or equivalently

  approxrealyear = (fakeyear - 1900) * 10 + 1000

except that 1791 is represented as 1971 as a special case because it's a nice anagram (it should have been 1979).
