In Genesis, how old is Noah when the Flood begins and he enters the Ark?

In Genesis, Noah is 600 years old when the Flood begins and he enters the Ark.

Genesis 7:6 states that Noah is six hundred years old when the waters of the Flood come upon the earth. The age is part of the genealogy and chronology that frame the story. Genesis 7:11 further dates the beginning of the Flood to the seventeenth day of the second month of Noah’s six-hundredth year.

This age is distinct from Noah’s age when his sons are born. Genesis 5:32 says Noah is 500 years old when he becomes the father of Shem, Ham, and Japheth, so the Flood narrative places the catastrophe roughly a century later. Genesis 9:28 then says Noah lives 350 years after the Flood and dies at 950.

The figure belongs to the biblical narrative’s unusually long lifespans for early human generations. It should not be confused with the age of the earth, the duration of the Flood, or the time required to build the ark.
