The new era of Japan has been announced.

For me, there was no question, "Reiwa or Leiwa?"

I know that "L" is out of scope.

In programming, "L" is pretty hard to recognize.

If "l" is written in lower case, it looks like "1" and also looks like half-width characters of "|".

So, i, k, m, n, p, etc. are used like "for (int i = 0; i <9; i ++)", but programs using "l" variable ,as a single, is rare to be seen.

Even in sentences,

It is easy to confuse even capital "L" with "「" and "」" .

In both official documents and private documents, the era number notation starting with "L" will cause confusion.

By the way, it is no reason that most of IT engineers have a desire to use "Reiwa 0", "R-0" as the first year of "Reiwa".

In the programming world, it is customary to count from "0", and in fact it is easy to calculate.

For example, array a [10] can contain up to a [0], a [1] ... a [9], but if trying to put a [10], it will result in an error or bug.

It is very difficult to explain this "feel" to non-programmers.

For example, it is uncomfortable that the 21st century started not from the year 2000 but 2001.

or, it is disgust that AC1 and BC1 are consecutive years

However, most people will not understand it.

Yes. I also know that you can not understand it.

For example, if the government announces that

"the New Year's Day will be 0 day in 0 month "

Without doubt, the Japanese government will be overturned be people.

I think that three hours will be enough.

And we can be witnesses of the world's shortest time of the coup.
