Final answer:
There are 2460 years between 1230 BCE and 1230 CE. This is calculated by adding the years in BCE to the years in CE, as BCE counts backwards to year zero and CE counts forward from year zero.
Step-by-step explanation:
To calculate how many years there are between 1230 BCE and 1230 CE, we acknowledge that the BCE/CE designation is a modern system for dating years that sets year zero as the reference point. BCE, which stands for "Before Common Era," counts backwards from year zero, and CE, which stands for "Common Era," counts forwards from year zero. Therefore, to determine the number of years between 1230 BCE and 1230 CE, simply add the years in BCE to the years in CE.
1230 BCE to year zero is 1230 years. Then, from year zero to 1230 CE is another 1230 years. So, when you combine both periods, the total number of years between 1230 BCE and 1230 CE is:
1230 years (BCE) + 1230 years (CE) = 2460 years
