View Full Version : Timescale question

10 years = decade
100 years = century
1000 years = millennium
1,000,000 years = ????

I googled but can't find a term. There seems to be no verbiage until a billion years, which is an aeon, although that word is used in a loose manner. It's not "era" because that's variable and applies to time periods with start and end points defined by events rather then strict time. Epoch is used elsewhere.

How about kilomillennium? :)

What's wrong with megayear?

How about "myriaury" -- 10,000 centurys. That has a nice "ring" to it.

I call it a m.y. (http://dictionary.reference.com/search?q=m.y.) :)

a million years is a millesimal in latin, or a Millesium

Ooo! We have a winner! I think.

But if I use it in a fiction, will it make a lot of people go "huh?". Or they'll think I just can't spell millennium. :)

Google returns 10 hits and asks if I meant "millenium". Yes, with one "n".

Hmm. Must ponder. I have to admit "kilomillennium" was something I made up for the post, but after floating about my head for a bit I kind of like it.

I am finding that Megayear (My) and Gigayear (Gy) are becoming more and more common in scientific articles
