calHeaderFormat
Header format for calendar mode
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. overrideCalHeaderFormat). For more information, please take a look at the
Localizing Datebox section.
This is a parsed format for the header (if shown) in CalBox.
For more information on date format variables, see: Output Formats
