The AD/BC notation does not use a
year zero
; however,
astronomical year numbering
does use a minus sign, so '2 BC' is equal to 'year -1', '1 BC' is equal to
astronomical 'year 0'
, and so forth. In the
Gregorian system
, the Nth century
AD
starts in the year (N-1)*100+1 and ends in year N*100, so for example, the
16th century
begins on
January 1
,
1501
and ends December 31st,
1600
.
However, year order is reversed in the
BC
era, so the Nth century BC
begins
in the year N*100 BC and
ends
in (N-1)*100+1 BC, so for example the
third century BC
begins in
300 BC
and ends
201 BC
.
