You got it almost right already! Use the "between" operator; *sometimes* SQL *is* intuitive:
E.g. in my database:

select run_name from runs where comp_date between '2001-may-10' and '2001-jun-5';
run_name | comp_date
------------------+------------------------
spcsil-103-RP | 2001-06-04 21:09:35-04
airtest_0120 | 2001-05-21 20:10:50-04
spcsil-101-RP | 2001-05-23 17:44:11-04
