Personally, I think the second day ("second" day as in the one allowed by the UI, not the "real" second day as sillysaurusx outlined) is much more interesting (https://news.ycombinator.com/front?day=2007-02-20) as it also features "Why we made this site (ycombinator.com)" (https://web.archive.org/web/20070305045009/https://ycombinat... - https://news.ycombinator.com/item?id=189) but when I made that submission, it got no traction (https://news.ycombinator.com/item?id=21206516) so happy to see that people care more about the "first" day :)
