How do we count centuries

We also sometimes see people confuse the "hundreds" form with the "century" one, referring to a date like as occurring in the "s. The thing to remember is that the number in the name of the century the 16th century, for example is always one higher than the number that starts the century's years: the years of the 16th century start with There's logic behind it, of course. The first century of the current era aka the 1st century CE or AD didn't start with ; it started with 1 more on the implications of that below.

It wasn't until the second century, aka the 2nd century, that the years had a digit in the hundreds column: the year was a century and a half into the new era, putting it smack-dab in the middle of the 2nd century. AD also styled A. AD is contrasted with BC also styled B. It depends on who you ask.

Some people think the 22nd century will start January 1, and end December 31, , with the 23rd century beginning on January 1, But there is a long history of people insisting that this is flat-out wrong for mathematical reasons: a century is by definition years in length, and the first century started on January 1, 1, which means that when December 31, 99 rolled around only 99 years had passed; therefore, the first century of the current millennium didn't actually end until December 31, , and the second century didn't begin until January 1, This topic has proven to be vexatious especially at the turns of centuries, starting at the end of the 17th one, according to a Library of Congress article by Ruth S.

Freitag called "Battle of the Centuries. We have uniformly rejected all letters, and declined all discussion upon the question of when the present century ends? The present century will not terminate till January 1, , unless it can be made out that 99 are Eighteen centuries are years, then how can 18 centuries be completed till the year has expired?

Thank you! The first century starts the 1st january of year 1 there is no year 0 in any Gregorian or Julian calendar. The second century starts years later so the first january and so on, the 21st century starts the 1st of january as the 3rd millennium , so currently the humanity lives in the 21st century. Before Christ, the principle is reversed, the 1st century before Christ starts the 1st january and ends the 31 december -1, included.

Between year 1 and year included, it is the first millennium. Between the year and the year is the second millennium.

Between the year and the year is the third millennium started on January 1, and will end on December 31, so currently we are in the 3rd millennium. We are currently in the 21th century which began on January 1, and that will end on December 31, Add 1 to the first 2 digits on the left of the year of birth, unless it is a year that ends in There was no century 0, so on January 1st of year 1 the first century began.

There is therefore a relation between the digit of hundreds of a date and the number of the century. The number of the century is equal to the number of hundreds increased by 1. The denomination "AD 1" for this year has been in consistent use since the mid -medieval period when the anno Domini AD calendar era became the prevalent method in Europe for naming years. The preceding year is 1 BC; there is no year 0 in this numbering scheme. But nobody really knows exactly when Jesus was born.

Some scholars think that he was born between 6 B. Although most Christians celebrate December 25 as the birthday of Jesus Christ, few in the first two Christian centuries claimed any knowledge of the exact day or year in which he was born. Using these methods, most scholars assume a date of birth between 6 and 4 BC , and that Jesus' preaching began around AD 27—29 and lasted one to three years. They calculate the death of Jesus as having taken place between AD 30 and Modern scholars date the birth of Jesus between 7 and 4 B.

Let's go with the 4 B. Jesus would be about 2, years old as of instead of that's because of a quirk in the Christian calendar in which there is no year zero it goes directly from 1 BC to AD 1. Abba Father is a common term used for the creator within Christianity because it was a title Jesus used to refer to God the Father.

It has different gospels than the Roman Catholic Bible. Mary's Father was a man named Joachim. Before she was married to Joesph her name was Batjoachim. The word "Bat" in Hebrew, means "becoming" so when she was born she was becoming. Some apocryphal accounts state that at the time of her betrothal to Joseph, Mary was 12 — 14 years old, and he was ninety years old, but such accounts are unreliable. According to ancient Jewish custom, Mary could have been betrothed at about
