Joda-Time: Test if a LocalDate falls in a duration

What is an efficient and easy-to-read expression of testing if LocalDate dayX falls in a duration that is described with a starting day LocalDate day0 and a length Period length?

Currently I am doing like this:

boolean match = !day0.isAfter(dayX) && day0.plus(length).isAfter(dayX);

I just feel this looks a bit dumb and every time I read this it takes several seconds for my brain to tell if the boundaries are correct. So I am looking for a smarter way that maybe involves the Duration or Interval classes.

Somewhat similar approach: day0 < dayx < (day0 + period)

boolean match =  (dayx.isAfter(day0) && dayx.isBefore(day0.plus(length));

What you are doing is correct (except that you need to use before method for the first condition). Maybe you can wrap it into a method and call it to make it reusable and look more elegant, e.g.:

public boolean isInRange(Localdate start, Period period, Localdate target){
   return !target.before(start) && !target.after(start.plus(period));
}
