推荐答案

区域设置不携带该信息。这是因为什么手段一周的第一天，取决于应用程序（上的每个的应用程序），不会在计算机上。

Locales don't carry that information. That's because what "first day of the week" means depends on the application (on each application), not on the computer.

我在哪里工作，某些应用程序把星期一作为一周的第一天，和其他人把星期日作为一周的第一天。华尔街这里日历全部采用星期日作为第一天;制造日历通常使用星期一。

Where I work, some applications treat Monday as the first day of the week, and others treat Sunday as the first day of the week. Wall calendars here all use Sunday as the first day; manufacturing calendars usually use Monday.

在Windows上，使用GetLocaleInfo（），但语言环境可以在运行时进行更改。它可以通过Windows API来设置。 GetLocaleInfoEx（）有更详细的文档。它看起来像SetLocaleInfo（）可以改变独立于其他区域设置一周的第一天。

Under Windows, use GetLocaleInfo(), but the locale can be changed at run time. It can be set through the Windows API. GetLocaleInfoEx() has more detailed documentation. It looks like SetLocaleInfo() can change the first day of the week independent of other locale settings.

在Linux下，也有用于识别区域设置实用的一周的第一天的规定。 （人5区域或区域设置文档的在线。搜索LC_TIME）。它记录为符合POSIX.2，ISO / IEC 14652

Under Linux, there are provisions for identifying the first day of the week in the locale utility. (man 5 locale, or locale docs online. Search for "LC_TIME".) It's documented as conforming to POSIX.2, ISO/IEC 14652.

$ locale day
Sunday;Monday;Tuesday;Wednesday;Thursday;Friday;Saturday

在我的语言环境的一周的第一天是星期天。

First day of the week in my locale is Sunday.

我还没有能够找到一个系统调用或库调用它。我没有源$ C ​​$ C派上用场了。

I haven't yet been able to find a system call or library call for it. I don't have the source code handy.
