2005 no year zero
This is possible if you are talking about years BC. Someone born in 2005 BC would be ten years old in 1995 BC and fifteen years old in 1990 BC.
30 years. 15 - -15 = 15 + 15 = 30.
10 years??30 years I believe, from -15 to +15 is 30
From 15 BC to 0, there is a timespan of 15 years. From 0 to AD 15, there is a timespan of 15 years. 15 + 15 = 30. So, 30 years. ========================================= From the end of 15 BC to the end of 15 AD = 30 years From the end of 15 BC to the beginning of 15 AD = 29 years From the beginning of 15 BC to the end of 15 AD = 31 years From the beginning of 15 BC to the beginning of 15 AD = 30 years 29: There was no year zero. AD1 follows BC1. Measure from same day in each year: From BC 15 to BC 1 there are 14 years (15 to 14 is 1 year etc) From BC 1 to AD 1 there is 1 year. From AD 1 to AD 15 there are 14 years. Total 29 years. Or, using the rule: Sobtract the two years from each other (count BC as negative) and then subtract another 1 if going from BC to AD and you get 15 - (-15) -1 = 29.
865 years. To get the answer, add 15 to 850.

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.
