On which day of which month did Genesis say the Ark came to rest?

Genesis says the Ark came to rest on the 17th day of the seventh month.

Genesis 8:4 gives this date when it says the ark rested on the mountains of Ararat. The statement appears after the waters had prevailed for 150 days and after Genesis says that God remembered Noah and caused a wind to pass over the earth.

The verse uses the calendar system of the biblical narrative rather than a modern named month such as January or July. Because the ancient calendar and the relationship between its months and modern calendars are matters of historical interpretation, the safest answer is the exact wording supplied by Genesis.

The date of resting is not the same as the date Noah and his family left the ark. Genesis continues describing the drying ground and says the occupants eventually emerged after receiving God’s command.
