The two notation systems are numerically equivalent: "2023 CE" and "AD 2023" each describe the current year; "400 BCE" and "400 BC" are the same year.
2023 CE refers to the year 2023 in Common Era. It is same as 2023 AD (Anno Domini) - i.e. 2023 years after the birth of Jesus Christ.
The year 2022 CE is the same year as 2022 AD. The Gregorian calendar, which is the dating system we use to measure years today, was created by a pope of the Catholic Church. That's why it marks time based on the birth of Jesus Christ.
we live in Holocene Epoch, of the Quaternary Period, in the Cenozoic Era (of the Phanerozoic Eon)
This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus, AD counting years from the start of this epoch and BC denoting years before the start of the era. There is no year zero in this scheme; thus the year AD 1 immediately follows the year 1 BC.
Jesus was born around 4 B.C. and was crucified in A.D. 30, according to the PBS FRONTLINE show "From Jesus to Christ." Britannica cites his birth year as ranging from 6 to 4 B.C. and has the same death year as Frontline.
The date of birth of Jesus is not stated in the gospels or in any historical sources, but most biblical scholars generally accept a date of birth between 6 BC and 4 BC, the year in which King Herod died.
An important reason for adopting BCE/CE is religious neutrality. Since the Gregorian calendar has superseded other calendars to become the international standard, members of non-Christian groups may object to the explicitly Christian origins of BC and AD.
The 1st century BC, also known as the last century BC and the last century BCE, started on the first day of 100 BC and ended on the last day of 1 BC.
The alternative to using BC and AD would be to use BCE, which means “before Common Era,” and CE, which means “Common Era.” Despite removing Christianity from the name, BCE and CE are still tied to the original Christian idea of BC and AD.

Common Era and Before the Common Era are alternatives to the original Anno Domini (AD) and Before Christ (BC) notations used for the same calendar era. The two notation systems are numerically equivalent: "2023 CE" and "AD 2023" each describe the current year; "400 BCE" and "400 BC" are the same year.
A monk called Dionysius Exiguus (early sixth century A.D.) invented the dating system most widely used in the Western world. For Dionysius, the birth of Christ represented Year One. He believed that this occurred 753 years after the foundation of Rome.
In the modern calendar, we label all years with B.C. (before Christ) or A.D. (anno domini, or "in the year of our lord"). There is no "zero" year -- in this system, the year Christ was born is 1 A.D., and the year preceding it is 1 B.C.
BC or B.C. means Before Christ. The year Christ was born is considered AD 1 and the year before that is labeled 1 BC. Historians use a nomenclature with less religious connotation: namely CE/BCE where CE means "Common Era" and BCE stands for Before Common Era.
As soon as 1 BC ends, AD 1 starts. So between the first of January 1 BC and the first of January AD 1, it's precisely one year. ? Our time calculator is our most diverse tool for calculations with time.
The birth of Jesus (pictured above) is widely regarded to have been placed by Dionysus Exiguus, inventor of the Anno Domini dating system, in 1 BC.
Jesus died, therefore, on Friday, April 3, AD 33 at about 3 p.m., a few hours before the beginning of Passover day and the Sabbath. This is the date in the Julian calendar, which had been introduced in 45 BC, and follows the convention that historical dates adhere to the calendar in use at the time.
The BC/AD system was invented by a monk named Dionysius Exiguus who was trying to establish a Christian chronology; before his time one had to use some system more or less tainted with paganism, such as the AUC system (from Rome's foundation) or consular dating ("the year when X and Y were [Roman] consuls" - by the ...
Simply put, BCE (Before Common Era) is a secular version of BC (before Christ). CE (Common Era) is the secular equivalent of AD (anno Domini), which means “in the year of the Lord” in Latin.
The reason some have adopted the use of C.E. rather than A.D. (“In the year of Our Lord” or “Anno Domini”) is to ease the minds of non-Christians who might object to this implicit acknowledgement of Jesus as Lord.
The terms BC and AD have clear Catholic roots. Dionysius Exiguus, an abbot in Rome, devised them as a way to determine the date for Easter for Pope St. John I. The terms were continued under the Gregorian Calendar, created in 1582 under Pope Gregory XIII.
Jesus' name in Hebrew was “Yeshua” which translates to English as Joshua. So how did we get the name “Jesus”?
“The real reason for the selection of Dec. 25 seems to have been that it is exactly nine months after March 25, the traditional date of Jesus' crucifixion. … As Christians developed the theological idea that Jesus was conceived and crucified on the same date, they set the date of his birth nine months later.”
