daysOfWeekShort
Abbreviated days of the week
This is a i18n option! i18n options can not be set directly on a per-instance basis, you must include the "override" directive, and properly camel case the new name - (i.e. overrideDaysOfWeekShort). For more information, please take a look at the
Localizing Datebox section.
Note that if you are relying on short day names to read a date back in (very rare, as there is almost always a more granular option available), and there are duplicates in this list (i.e. array(‘S,’M’,’T’,’W’,’T’…) ) the parser will likely behave very strangely.
