According to the ICS timescale, time divisions are as follows:

Age (1 million years, 1000 Millennia).
Epoch (10 million years, 10 Ages).
Era (100 million years, 10 Epochs).
Eon (500 million years, 5 Eras.

But, the ICS timescale does not use lustrum, decades, centuries or millennia. Calendar subdivisions use them and according to it, nothing follows millennium. Anything longer than 1 millennium is just referred to as Millennia (Plural form of Millennium).

The next unit of time after a millennium is a "megayear." One megayear is equivalent to one million years. This term is not commonly used in everyday language but is sometimes utilized in scientific contexts when discussing geological or astronomical timescales.

What is equals to a thousand years?

Since we are now in the year 2010. You can think about words that you might have heard used to describe groups of years.You have a decade, which refers to 10 years. Examples of years in a decade would be for the 1990's for example, and you would have the years 1990-1999; or the 1960's which would be 1960-1969.Then, the next highest grouping of years would be a century, which is 100 years. These are a bit tricky to convert. You would talk about the 17th century, but mean the 1600's (sixteen huindreds); or mention the 20th century, but mean the 1900's (nineteen hundreds). This is due to how number groupings happen.Think about how your age is discussed. That from birth to age 9, you were in your first decade, but your age was 0-9. Your second decade began with age 10-19 (even though your age was written with a "1" it was still your second decade of living), and so on. So, at age 31, you would be in your fourth decade.So, getting back to year grouping names you began with year, then decade, then century, and the next grouping, would be a millennium.A millennium would be one thousand years! And if you notice, we are in year 2010--having begun our third millennium! (remember the silly way that number groupings happen) because from the year zero a.d. to 999a.d. would be the first millennium, then from 1000a.d. to 1999a.d. you would have the second millennium, and from 2000a.d. to 2999a.d. you would be in your third millennium.


How many millennium in 10 decade?

1 decade = 10 years ⇒ 10 decades = 10 x 10 years = 100 years 1000 years = 1 millennium ⇒ 10 decades = 100 years = 100 ÷ 1000 millennium = 1/10 millennium = 0.1 millennium


How many millennium in a decades?

A millennium is 1000 years. A decade is 10 years. Thus there are 1000 / 10 = 100 decades in a millennium.
