First the rain fell for 40 days (during this time the waters reached their great depth). See Genesis 7:4.
Then the waters prevailed upon the earth (that is, the waters maintained their great depth) for 110 days (Genesis 7:24).
Next, the waters were “going and decreasing” for 74 days (Genesis 8:5).
After 40 more days Noah sent out the raven (Genesis 8:6-7).
After 7 more days Noah sent out the dove for the first time (Genesis 8:8 and compare 8:10).
After 7 more days he sent the dove for the second time (Genesis 8:10).
After 7 more days Noah sent out the dove for the third time (Genesis 8:12).
After 86 more days the earth had dried to the point where they could depart from the ark and settle elsewhere (Genesis 8:13-14).
TOTAL DAYS IN THE ARK: 371
Thus, Noah and his family spent more than a year in the ark!
Note: For a more detailed analysis of these calculations, see The Genesis Flood, by John Whitcomb and Henry Morris, p. 3.
