Обсуждение: Number of days

Is there a function that returns the number of days between two dates?
I found only age, which calculates the difference between two timestamps,
but the example shows the result as a timestamp.
Thanks,

Subtraction.

regression=# select '27 Feb 2001'::date - '5 Jan 2001'::date;
 ?column?
----------
       53
(1 row)

            regards, tom lane

select date_part('day','@ 4 days 3 hours 2 mins');

date_part
---------
        4
