Translators: Some languages need different grammatical forms of
* month names depending on whether they are standalone or in a complete
* date context, with the day number.  Some may prefer starting with
* uppercase when they are standalone and with lowercase when they are
* in a full date context.  However, as these names are abbreviated
* the grammatical difference is visible probably only in Belarusian
* and Russian.  In other languages there is no difference between
* the standalone and complete date form when they are abbreviated.
* If your system is Linux with the glibc version 2.27 (released
* Feb 1, 2018) or newer then you can refer to the date command line
* utility and see what the command `date +%Ob' produces.  Also in
* the latest Linux the command `locale ab_alt_mon' in your native
* locale produces a complete list of month names almost ready to copy
* and paste here.  Note that this feature is not yet supported by any
* other platform.  Here are abbreviated month names in a form
* appropriate when they are used standalone.
