Provides a consistent vector representation of years with an
associated calendar era or time scale. It includes built-in definitions of
many contemporary and historic calendars; time scales commonly used in
archaeology, astronomy, geology, and other palaeosciences (e.g. Before
Present, SI-prefixed 'annus'); and support for arbitrary user-defined eras.
Functions for converting between eras and for type-stable arithmetic with
years are also provided.

Provides a consistent representation of year-based time scales as a
numeric vector with an associated 'era'. There are built-in era definitions
for many year numbering systems used in contemporary and historic calendars
(e.g. Common Era, Islamic 'Hijri' years); year-based time scales used in
archaeology, astronomy, geology, and other palaeosciences (e.g.
Before Present, SI-prefixed 'annus'); and support for arbitrary user-defined
eras. Years can converted from any one era to another using a generalised
transformation function. Methods are also provided for robust casting and
coercion between years and other numeric types, type-stable arithmetic with
years, and pretty-printing in tables.
