ThreeTen-Extra provides additional date-time classes that complement those in JDK 8.

Not every piece of date/time logic is destined for the JDK. Some concepts are too specialized or too bulky to make it in. This project provides some of those additional classes as a well-tested and reliable jar.

Various documentation is available:

• The home page
• The user guide
• The Javadoc

Release 1.8.0 is the current release. This release is considered stable and worthy of the 1.x tag as per SemVer.

ThreeTen-Extra requires Java SE 8 or later and has no dependencies.
