Bc in mail

You're referring to the "Before Christ" notation in dates!

BC stands for "Before Christ", which is used to indicate a date that occurred before the birth of Jesus Christ. It is commonly used in conjunction with AD (Anno Domini, or "in the year of the Lord" in Latin), which indicates a date after the birth of Jesus Christ.

For example:

• 1000 BC: This date occurred 1000 years before the birth of Jesus Christ.
• 2023 AD: This date occurred 2023 years after the birth of Jesus Christ.

It's worth noting that the use of BC and AD dates is not universally accepted, and some cultures and calendars use different systems to measure time. However, the BC/AD system is widely used in Western cultures and is a common way to express dates in history and literature.
