Answer 2

• The period before that is known as B.C. (short for Before Christ) and the years after are known as A.D (short Anno Domini, and meaning the Year of our Lord).
• What can make this system confusing is that events in the B.C. era are dated in descending order, whilst those in the A.D. era happen in ascending order.
• 1 AD is similar to zero on the number scale. All dates before it is are as BC (Before Christ), whereas all dates after it including it are as AD (Anno Domini - Latin for 'The Year of the Lord').
• So, 2000BC is older than 1400BC which is older than 1AD older than 1400AD older than 2000AD, now simply called the year 2000.

hope it helps
