One of these (the YEAR format element) allows us to format a date with the year spelled out. For example, instead of 1972, we’d get NINETEEN SEVENTY-TWO.
We can also use SYEAR so that BC dates are prefixed with a minus sign (-).
MariaDB has a lc_time_names system variable that controls the language used by the DAYNAME(), MONTHNAME() and DATE_FORMAT() date and time functions.
