What Are BC and AD?
In the Gregorian calendar, BC refers to years before the birth of Christ, while AD stands for "Anno Domini," Latin for "in the current year of our Lord." These terms are used to label years in historical timelines.
For example, 100 BC occurred 100 years before 1 AD. Modern alternatives to these terms CE and BCE include BCE (Before Common Era) and CE (Common Era), which serve as secular replacements for BC and AD, but the actual year numbering remains the same.
How to Convert BC to AD
Converting between BC and AD is straightforward once you understand the basics of the system. Here's the fundamental BC to AD conversion formula:
BC year + AD year = total number of years between the two dates.However, note that 1 BC is immediately followed by 1 AD. There is no "year zero" in the Gregorian calendar. This is important for making accurate calculations.
Example: Calculating the Difference Between BC and AD
Let’s say you want to calculate how many years ago have passed from 50 BC to 2024 AD. The formula is simple:
2024 + 50 = 2074 years.By adding the years together, you get the total number of years between these two dates, across the BC and AD divide.

The Gregorian Calendar and the Birth of Christ
The Gregorian calendar, introduced in 1582, replaced the Julian calendar and is the most commonly used dating system for keeping time today. It revolves around the birth of Christianity, with BC representing years before this event and AD denoting the years after. Despite its Christian era, the calendar is used globally for secular purposes, although BCE and CE are now popular alternatives.
How Does the Timeline Work?
In the BC to AD timeline:
- 1 BC is the last year before Christ’s birth.
- 1 AD is the first year after Christ’s birth.
- There is no year zero; the timeline jumps directly from 1 BC to 1 AD.
This lack of a year zero is a key detail when performing date calculations, as it affects the total count of years.
Common Questions About BC and AD
Is There a Year 0?
No, the Gregorian calendar does not have a year zero. The transition moves directly from 1 BC to 1 AD. This can sometimes confuse people when calculating BC and AD dates, but it’s an important distinction for accurate date conversions.
What is 1 AD?
1 AD marks the first year after the birth of Christ, and it’s where the Anno Domini (AD) era begins. Similarly, 1 BC is the last year before Christ’s birth.
