Epoch Counter

Dionisius Exiguus, a Catholic monk, in the year 600
devised the Anno Domini calendar system that is still
used all over the world today (abbreviated as AD or
BC). The calendar era to which it refers is based on
the traditionally reckoned year of the birth of Jesus
of Nazareth, the central figure in Christianity, with AD
denoting years after the start of this epoch, and BC
denoting years before the start of this epoch. Anno Domini
is sometimes referred to as the Common Era, Christian
Era, or Current Era (abbreviated as C.E. or CE). CE is
often preferred by those who desire a term not explicitly
related to Christian conceptions of time. The Epoch
Counter is a manual / annual device that allows one to
display the year using a set of wooden modules, each
bearing a different cultural reference to the epoch.
