Six years almost to the day. The "official" beginning date is usually said to be September 1, 1939, when Germany invaded Poland. This ignores the fact that Japan had invaded China in 1937, and Manchuria in 1931. The end came in 1945, with Germany giving up in May, and the Japanese signing surrender documents aboard the US battleship Missouri September 2, 1945 in Tokyo Bay.
The year 1 BC was immediately followed by the year 1 AD. So from the end of 25 BC to the end of 1 BC was 24 years and from the beginning of 1 AD to the beginning of 16 AD was 15 years. So the number of years between the 25 BC and 16 BC = 24 + 15 = 39 years.
if you look at it as starting in 1939 then six years passed
The beginning of 2013 is 88 years before the beginning of the 22nd century.
