A new date and date/time library designed for C++14 is presented. This library stresses ease of use, easy-to-read code, catching common errors at compile time, and uncompromising run-time performance.

The design starts with the C++11 std::chrono library, and extends it into the realm of calendars, giving a seamless experience built upon chrono::system_clock::time_point, the durations you already know such as chrono::hours and nanoseconds. Functionality that allows easy and efficient conversions between the std::chrono types and year/month/day - hh::mm::ss data structures is presented.

When dates (and times) are known at compile-time (e.g. leap second transitions), all computations are available at compile time (constexpr). When only parts of a date are known at compile time, run-time efficiencies are still gained by compile-time computing parts of the date.

The syntax of the library is built around a few easy-to-learn rules, and strictly checked at compile time. This makes it easy to learn, and very forgiving for the novice.
