Java: Difference between two dates in Months

Question

How can I find the difference between two Dates in units of whole months, in Java?

@anon If you edit to define exactly what you mean by "whole months", this Question could be re-opened and might prove quite useful. — Basil Bourque, Nov 15 '16 at 21:51

Using JodaTime a lot of date/time functionality is a lot easier to implement:

http://joda-time.sourceforge.net/

there were plans to incorporate the library into Java 7, though this unfortunately did not happen:

Joda Time to be included in Java 7?

Most likely the new date and time API is going to be included in Java 8 - see [Project ThreeTen](http://threeten.sourceforge.net). – Jesper Sep 28 '12 at 09:36

I would strongly recommend looking at Joda-Time since it's a better, more-intuitive and thread-safe API. Check out this SO answer for a Joda-specific answer to your question.

Note that the Joda API was the foundation for the new Java Date API (JSR-310) and is scheduled for release in Java 8 (it got dropped from Java 7). It's a de facto standard and learning that API will be valuable.
