1st parameter – the full date By default YYYY-MM-DD format becomes month-day-year format and DD-MM-YYYY format becomes day-month-year while other formats remain in the order they are input. Abbreviated months are accepted and are abbreviated in the output. Capitalisation and comma mistakes are corrected.
Alternatively, a format for duration based on combined date and time representations may be used by agreement between the communicating parties either in the basic format PYYYYMMDDThhmmss or in the extended format P[YYYY]-[MM]-[DD]T[hh]:[mm]:[ss]. For example, the first duration shown above would be "P0003-06-04T12:30:05".
Speaking the "day month year" format is much less common, with the exception of holidays such as the Fourth of July. The year-month-day order, such as the ISO 8601 "YYYY-MM-DD" notation is popular in computer applications because it reduces the amount of code needed to resolve and compute dates.

<date formatting style> controls the date format in which the result is to be emitted. Recognized values for the second parameter are: DMY gives d mmmm yyyy (e.g. 31 May 2007). This is the default format. MDY gives mmmm d, yyyy (e.g. May 31, 2007) YMD gives yyyy mmmm d (e.g. 2007 May 31) ISO gives an ISO 8601 style yyyy-mm-dd (e.g. 2007-05-31)
TIMESTAMP: This is a DATE and a TIME put together in one variable (e.g. 2011-05-03 15:51:36.123456). TIMESTAMP WITH TIME ZONE: the same as TIMESTAMP, but including details about the time zone in question. The SQL function EXTRACT can be used for extracting a single field (seconds, for instance) of a datetime or interval value. The current ...
Since portions of the population continued to use the old format, the traditional format was re-introduced as alternative to the standard YYYY-MM-DD format to DIN 5008 in 2001 and DIN ISO 8601 in September 2006 but its usage is restricted to contexts where misinterpretation cannot occur. The expanded form of the date (e.g., 31.
