21st century

The 21st century is the current century of the Anno Domini era or the Common Era, in accordance with the Gregorian calendar. It began on January 1, 2001, and will end on December 31, 2100. It is the first century of the 3rd millennium. It is distinct from the century known as the 2000s, which began on January 1, 2000 and will end on December 31, 2099.

Transitions and changes

The first years of the 21st century have thus far been marked by the rise of a global economy and Third World consumerism, mistrust in government, deepening global concern over terrorism and an increase in the power of private enterprise. The longterm effects of increased globalization are not known, but there are many who are concerned about its implications. The Arab Spring of the early 2010s led to mixed outcomes in the Arab world. The Digital Revolution which began around the 1980s also continues into the present. The Millennials (born c. 1981-2000) having been born before the turn of the century give way to the rise of Generation Y & Generation Z in Western countries.

Century

A century (from the Latin centum, meaning one hundred; abbreviated c.) is 100 years. Centuries are numbered ordinally in English and many other languages (e.g. "the 7th century AD/CE"). A centenary is a hundredth anniversary or a celebration of this, typically remembrance of an event which took place a hundred years earlier; and its adjectival form is centennial.

Start and end in the Gregorian Calendar

According to the Gregorian calendar, the 1st century AD/CE started on January 1, 1, and ended on December 31, 100. The 2nd century started at year 101, the 3rd at 201, etc. The n-th century started/will start on the year (100 × n) − 99 and ends in 100 × n. A century will only include one year, the centennial year, that starts with the century's number (e.g. 1900 is the final year in the 19th century).

1st century BCE and AD

There is no "zeroth century" in between the 1st century BCE and the 1st century AD. Also, there is no year 0 AD. The Julian calendar "jumps" from 1 BCE to 1 AD. The first century BCE includes the years 100 BCE to 1 BCE. Other centuries BCE follow the same pattern.
