only 200 years :)
To calculate the number of years between 2000 BC and AD 1788, you add the years before Christ (BC) to the years after Christ (AD). This is done by adding 2000 years (from 2000 BC to 1 BC) and 1788 years (from AD 1 to AD 1788), which totals 3788 years. Therefore, there are 3788 years between 2000 BC and AD 1788.
There are 23 years between 1988 and 2011.

That depends on exactly what you mean by "between": if you want the number of whole years that are after 1988 but before 1999, that's 10 (1989, 90, 91, 92, 93, 94, 95, 96, 97, 98). If you want the number of years between, say, April 5, 1988, and April 5, 1999, that's 11.
