In the six hundredth year of Noah’s life, on the seventeenth day of the second month— on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened.
Genesis 7:11

So, it says in Genesis 7:11 that the flood that Noah built his ark for started on the seventeenth day of the second month. Were the months and calendar system stuff different back then?? If not, then happy Noah’s ark day!
