            Bug ID: 24682
           Summary: zh_CN first weekday should be Monday per GB/T
                    7408-2005
           Product: glibc
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: localedata
          Assignee: unassigned at sourceware dot org

GB/T 7408-2005 Section 3.28

The first day of the week in China (Mainland) should be Monday according to the
national standard GB/T 7408-2005 [1]. It is also true in terms of common
perception, speaking as someone who was born there and has lived there 20+
years.

I think we need something like "first_weekday 2" to
https://sourceware.org/git/?p=glibc.git;a=blob;f=localedata/locales/zh_CN;h=62a46415c1567ed38d58140312cef11eed46092c;hb=HEAD

The issue was found in glibc 2.28 on Fedora 29 affecting the display of "GNOME
Calendar" [2] and is also present at git master HEAD. I believe it is better
for this to be fixed upstream.

saying "A calendar week starts with Monday".)

Thank you for the report.  Unfortunately, I can't read Chinese.  Also
unfortunately CLDR which is our most authoritative source still says it should
be Sunday. [1] Can you please file a new ticket in CLDR so we get some feedback
from them? [2] [3]

Thanks for the pointers. I found the same issue was raised there at CLDR:
https://unicode-org.atlassian.net/browse/CLDR-11510 . I've mentioned the
information I have there just now.

Good, let's see what's their feedback. If they don't answer anything by the end
of this development cycle then I think I will accept your proposed changes but
for now let's give them some time.

I am sorry, I was going to fix this just before the 2.30 release but I forgot. 
It is fixed now in master for the future 2.31 release.  I will try to backport,
though.

The same as in bug 24200 comment 2 I decided to introduce the same change to
all *_CN locales because CLDR assigns the first weekday to whole territory (all
languages if there are multiple).
