According to Genesis, how old was Noah when the floodwaters dried from the earth?

According to Genesis, Noah was 601 years old when the floodwaters had dried from the earth.

Genesis 8:13 says that in Noah’s 601st year, on the first day of the first month, the surface of the ground was dry. The verse marks a late stage of the flood narrative, after the Ark had rested, the waters had receded, and Noah had removed the Ark’s covering to inspect the land.

This age is distinct from the age given when the flood began. Genesis says Noah was 600 years old when the waters came, so the drying of the earth occurs during the following year. It is also different from Noah’s total lifespan: Genesis 9:29 records that he died at 950.

The chronology is one reason the story is often treated as a carefully dated sequence. Genesis gives ages, months, and days at several stages, although interpretations of the exact calendar system vary among readers and traditions.
