MySQL simple question on dates

Is it possible to be able to have an SQL query that is able to search through dates with +/- a few days?

For example if looking for a record with a date on 2009-04-01, could it be expanded to have a range from 2009-03-30 -> 2009-04-03?

I can guess you are able to do something like:

select * from 'something' where date < '2009-04-03' and date > '2009-03-30';

But I am not sure how to get it so that it adds/decreases the dates for the search statement

Thanks

ok thanks, worked like a charm 😀
