Calendars

[William Lahti]

I am trying to implement EnumCalendarInfo and would like to know if any
locales have multiple calendars, where the settings for the extra calendars
would be in the nls file, and if any calendars have their own seperate
file.

I'm not familiar with the Windows API in that respect, but I can tell 
you that both Jews and Muslims have their own calenders (as well as 
Chinese, Hindus etc, IIRC). At least in Israel, the gregorian is the 
main calender, but having the ability to view Jewish dates would be nice.

http://libhdate.sourceforge.net/ (Hebrew dates)

There is (or used to be) also a project with the same name for Muslim 
dates, but I can't seem to locate it. The best I can do is

Japanese also use a different system to indicate the
year. They use the year of the emperor. For example
today's year is 14 Heisei (The current emperor has
been in power scense 1990.)  When Emperor Hirohito
died in 1989, Japanese programmers had to reprogram
thier computers to deal with the new "year" as many
were hard-coded for the old emperor. Y2K wasn't much
of a problem because the Japanese had updated thier
computers ten years pervious.

Nowadays on computers, they simply list the julian
year, then month, then day, and then the character of
day of the week

2002(sei)/05(getsu)/14(hi) (Getsuyobi)

abbreviated, it looks like this --> 04.05.24

Here;s what the command "date" gave me as output

2004年  5月 24日
月曜日

Here's what cal gives me...

5月 2004
日 月 火 水 木 金
土
                   1
 2  3  4  5  6  7  8
 9 10 11 12 13 14 15
16 17 18 19 20 21 22
23 24 25 26 27 28 29
30 31

Just remeber, year comes first and  the date is
seperated by periods if you want to drop the
characters.

Don't get me started about representation.

First - the dates. Arabic dates are a bit simpler - it's a lunar 
calender (from moon birth until moon birth), which means that the months 
jump around the year. So, for example, Ramadan, the fasting month, can 
happen during winter or summer.

As for the Hebrew calender....
It's a lunar calender, with a leap MONTH added once every three to four 
years, to make sure it doesn't drift too far away from the seasons. So 
my birthday, which according to the Hebrew calender happens on the 21st 
of the SECOND Adar........

Then there is representation. Numerological letters are used. aleph 
means 1, bet means 2, yod means 10, kaf (the next one) means 20, and so 
on until 90, and then Kof means 100, and Taf (the last letter) means 400 
(22 characters altogether). The numbers are added, so this year is ���"� 
(Taf - 400 Shin- 300 Samech - 60 Daled -4, 764 altogether).

Of course, this is omiting the thousands. The real year is �'���"�, or 
5764. I was never sure what it's counting from. Naturally, the months 
are also displayed like that.

Oh, and did I mention that a day ends at sunset? Sabbath is kept from 
the sunset on Friday (actually, half hour before as a safty measure) 
until sunset on Saturday (half hour after).
