Averaging dates in oracle sql

Question

Is there a way to average multiple dates in oracle? avg doesn\'t do any good.

Thanks.

The 'median' function in oracle in a neat way does exactly what other answers do.

Here is a link to the Oracle documentation - https://docs.oracle.com/cd/B19306_01/server.102/b14200/functions086.htm

It can take as an arg a numeric datatype or a non-numeric datatype that can be converted implicitly to a number.

SQL> desc x1
Name                                      Null?    Type
----------------------------------------- -------- ----------------------------
A                                         NOT NULL NUMBER
D                                                  DATE

SQL> select * from x1;

     A D
---------- ---------
     1 11-DEC-14
     2 13-DEC-14
     3 22-DEC-14
     4 02-DEC-14
SQL> select median(d) from x1;

MEDIAN(D)
---------
12-DEC-14
