Different stages of Age?

[dingodoo]

What are the different stages of age in a gecko.

Obviously new born is 1 day oold, but what period of age is the gecko known as a juvinile and when does it become an adult

 

[Dog Shrink]

There's hatchling, juvenile sub-adult and adult. At which age the leo phases to the next catagory I am uncertain, but my breeder called my leo a sub-adult at 7 mos old.
