How many years between 400BC and 1500AD?

Answer 1

To find the number of years between 400 BC and 1500 AD, we need to calculate the difference between the two dates.

First, let's convert 400 BC to BC to AD: 400 BC is equal to 400 years before the start of the AD era. Since the AD era starts at 1 AD, we add 400 years to 1 AD to get: 400 BC + 400 years = 1 AD

Now, we can calculate the difference between 1 AD and 1500 AD: 1500 AD - 1 AD = 1499 years

So, there are 1499 years between 400 BC and 1500 AD.
