this is the list of patterns for date formats that this module recognizes.  Approximately the first half of these
  −
patterns represent formats that might be reformatted into another format.  Those that might be reformatted have
  −
'indicator' letters that identify the content of the matching capture: 'd' (day), 'm' (month), 'a' (anchor year),
  −
'y' (year); second day, month, year have a '2' suffix.
  −
  −
These patterns are used for both date validation and for reformatting.  This table should not be moved to ~/Configuration
  −
because changes to this table require changes to check_date() and to reformatter() and reformat_date()
