The year 1 BC / BCE is numbered 0, the year 2 BC is numbered − 1, and in general the year n BC / BCE is numbered "−( n − 1 )" ( a negative number equal to 1 − n ).

The numbers of AD / CE years are not changed and are written with either no sign or a positive sign ; thus in general n AD / CE is simply n or + n.
