According to Genesis, on which day did Noah remove the Ark’s covering?

According to Genesis, Noah removed the Ark’s covering on the first day of the first month. Genesis 8:13 says that by this date the ground had become dry, and Noah then looked out and saw that the surface of the ground was drying.

The date belongs to a detailed sequence of observations after the waters began to recede. Noah first sent out a raven, then released a dove several times. Later, the Ark came to rest on the mountains of Ararat, and Noah waited for further signs that the land was ready.

The wording is not a modern named calendar date. Genesis uses month and day numbers within the ancient calendar system assumed by the narrative. The account later says Noah left the Ark on the 27th day of the second month, making the period between uncovering the Ark and leaving it significant.

This detail is easy to confuse with the date the Ark rested or the date Noah first sent out a bird. Those events occur earlier in the sequence. The specific action here is Noah removing the covering after the ground had dried.
