36 : * - %A => long_weekday_format - Full name Ex: Tuesday
37 : * - %a => short_weekday_format - Three letter abbreviation Ex: Tue
38 : * - %B => long_month_format - Full name Ex: October
39 : * - %b => short_month_format - Three letter abbreviation Ex: Oct
40 : * - %x => standard_format_specifier - defined by the locale
41 : * - %Y-%b-%d => default_date_format - YYYY-Mon-dd
42 : *
43 : * Default month format == %b
