How to get an inclusive interval when using daterange

Hi,
I have a table* availability* which contains 3 columns: * id, product_id
and period_availability(type daterange).*

When I insert a data into this table I use this query:
insert into availability values ('product x', daterange('2018-02-02',
'2018-03-01', '[]')

So I get a period like this: [2018-02-02, 2018-03-02)
In my app I tried to subtract a day from the period when I got it from
database.I'm using daterange and not tsrange because the daterange gives me
less execution time when I make tests with a huge number of data.So is
there any way to get an inclusive interval with daterange or I have to use
tsrange to get inclusive intervals?
