Joda-time is a very easy-to-use, efficient class library for processing dates and times, and it's easier for a person to think than the JDK's own date/time class library.

Joda-time another date and time becomes very easy to manage, operate, and understand. The JDK and Joda-time can interoperate with each other, so there is no need to replace all of their code, only the part of the code that performs date/time calculations.
