The Devonian Period began approximately 419 million years ago, while the Pennsylvanian Period started around 323 million years ago. This results in a separation of about 96 million years between the beginning of the Devonian and the beginning of the Pennsylvanian.

The bible was written over a period of 1500 years.
Twenty years
If I remember right its 7 years
The Silurian period was between 443.7 - 416 million years ago, which means that it lasted around 27.7 million years.
144 to 65 Million Years Ago
There were three wars over a period of 120 years.
2191 if there is one leap year during that period and 2192 if there are two leap years during that period.
roughly 9 but it differs
The Cretaceous period occurred approximately 145 to 66 million years ago.
The average age of menarche (first period) is 13 years old. Anything between 10 years old and 16 years old is considered normal.
259 years (480-221 BC)
