Aastatuhandel

Aastatuhandel is the Estonian word for millennium. A millennium is a period of time that lasts for exactly one thousand years. The concept of a millennium is often used in historical and chronological contexts, particularly when discussing long periods of human history or geological time. It is a significant unit of time for understanding the progression of civilizations, the development of cultures, and major shifts in societal structures.

The current millennium, the third millennium CE (Common Era), began on January 1, 2001, and will end on December 31, 3000. Each millennium is divided into ten centuries, and each century into ten decades. The numbering of millennia is typically based on the Julian-Gregorian calendar system.

The idea of a millennium has also held religious and philosophical significance in various cultures. For instance, in some Christian traditions, a millennium refers to a period of 1,000 years mentioned in the Book of Revelation, often associated with a time of peace and righteousness. This theological concept has influenced art, literature, and social movements throughout history. In a broader sense, the term "millennium" can be used metaphorically to describe a very long and significant period, even if it doesn't precisely equate to 1,000 years. The Estonian word "aastatuhandeid" is the plural form, meaning millennia.
