To calculate the years between 250 AD and 50 BC, you need to add the two time periods together. There are 250 years from 1 AD to 250 AD, and 50 years from 50 BC to 1 BC. Therefore, the total is 250 + 50 = 300 years between 250 AD and 50 BC.
250 AD is later than 250 BC. Translation: 250 years after christ is later than 250 years before christ/

The year 250 AD and 250 BC refer to two different eras in the Gregorian calendar, with AD (Anno Domini) denoting years after the birth of Jesus Christ and BC (Before Christ) denoting years before that event. Specifically, 250 AD is 500 years after 250 BC. The two periods are separated by the transition from BC to AD, with no year zero in between. Thus, they represent different points in history, one in the Common Era and the other in the years preceding it.
