What is BC and AD?

The video tutorial explains the historical dating systems BC (Before Christ) and AD (Anno Domini), which are based on the birth of Jesus Christ. It provides examples, such as 55 BC and 410 AD, to illustrate how these terms are used. The tutorial also introduces alternative terms BCE (Before the Current Era) and CE (Current Era), which are used to accommodate non-Christian perspectives while still using the same historical reference point.
