2021 (MMXXI) is the current year, and is a common year starting on Friday of the Gregorian calendar, the 2021st year of the Common Era (CE) and Anno Domini (AD) designations, the 21st year of the 3rd millennium, the 21st year of the 21st century, and the 2nd year of the 2020s decade.
What is the current year in AD?
The Dionysian era distinguishes eras using the notations BC (Before Christ) and AD (Latin: Anno Domini, in [the] year of [the] Lord). The two notation systems are numerically equivalent: 2021 CE and AD 2021 each describe the current year; 400 BCE and 400 BC are each the same year.
What does AD mean after a year date?
Anno Domini AD stands for Anno Domini, Latin for “in the year of the Lord”, while BC stands for “before Christ”.
Why do BC dates go backwards?
Why do we count backwards for BCE dates? When we count dates in ancient history, the dates often appear backwards to us (for example, circa 30,000-20,000 BCE). This is because these dates happen before the year zero, and so we counting forward towards zero.
