There are 60 years between 30 BC and 30 AD. This is because there is no year 0; the calendar transitions directly from 1 BC to 1 AD. Therefore, you add the 30 years from 30 BC to 1 BC and the 30 years from 1 AD to 30 AD.
There are 30 years from 20 BC to 10 AD. This is true because it goes 20 to 0 to 10, adding up to 30.
what is that...
58 years are between 30 BC and AD 30. The first thing you need to remember is that there is no year 0; the year before AD 1 is 1 BC. So the years between 30 BC and AD 30 are... 29 BC, 28 BC, 27 BC, ..., 2 BC, 1 BC, AD1, AD 2, ..., AD 27, AD 28, AD 29 29 BC through 1 BC is 29 years, and AD 1 through AD 29 is 29 years. 29 years + 29 years = 58 years
AC is alternating current and AD is Anno Domini or after Christ.
To calculate the difference between 1000 BC and 2010 AD, you add the two years together since there is no year zero in the transition from BC to AD. This results in a difference of 3010 years (1000 years from 1000 BC to 1 AD, plus 2010 years from 1 AD to 2010 AD). Thus, there are 3010 years between 1000 BC and 2010 AD.
"Ad" is an abbreviation for "advertisement."

To calculate the years between 30 BC and 45 AD, you need to add the years before Christ (BC) to the years after Christ (AD). There are 30 years from 30 BC to 1 BC, and then 45 years from AD 1 to AD 45. Therefore, the total is 30 + 45 = 75 years.
