Years in 20x? format

[e***@virtualfon.com.ar]

I'm reading the "Finances" book by Bodie and Merton. In it, years are
usually noted as:

20x1, 20x2, 20x3, etc.

Since the book doesn't explain it, I did some Google searches and found
many sites that use this type of notation, but no explanations
whatsoever.

I understand it to mean:

2001, 2002, 2003, etc.

But still have some questions:

- Why use this notation?
- How are decades expressed with it? How would you write 1991? 1981?
2011?

It is typically textbooks which make notations in this format. Usually
because the book is published with the expectation that it will continue to
be published for decades, although there usually are revisions due to
changes in GAAP and laws.

So, if you were to be studying in 2015, then 20x8 would for the purposes of
the lesson and the exercises, be 2018.

Then, for a text published in, say, 1975, you would express something like
19x9 to mean either, 1979, 1989 or 1999.

The "x" is simply a placeholder.

Thanks for the answer.

I was confused at first since I found the notation being used in many
non-educational sites. However I think I can assume that those I saw
where actually examples, models, etc.
