Given that based on the formation of the calendar we are utilizing, the 1st Century started from year 1 to the first 100 years. This is based on the principle that there was nothing like year zero. Thereby the 2nd Century began from and lasted between the years 101 to 200.
Therefore, it is inferred that for example for the 9th Century B.C.E. we are citing the years 900 to 801 B.C.E.
Hence, for the year 893 B.C.E., we have 9th century BCE.
