What is the Common Era?

The Common Era (CE) and Before the Common Era (BCE) are ways to talk about years. They help us share dates without using special words from one religion. For example, β€œ2026 CE” means the same as β€œAD 2026,” and β€œ400 BCE” is the same as β€œ400 BC.”

Why Do We Use CE and BCE?

People use CE and BCE so that everyone, no matter what they believe, can talk about years together. This makes sharing history easier and kinder for all. Teachers, museums, and books often use these words to be fair to everyone.

How We Write the Years

When we write a year with BCE, we put it after the number. For example, 399 BCE is the same as 399 BC. For CE, we also put it after the year, like 2026 CE or AD 2026. Both ways tell us the same year, just with different names.

Many places around the world use CE and BCE to make dates clear. This helps everyone understand each other better when talking about the past or future.
