You can look at previous HN front pages. Here's yesterday: https://news.ycombinator.com/front?day=2017-05-24.
(We count 'day' using UTC so there's overlap with today depending on where you are.)

The article sets of adjacent days intersect. A merging query of recent days would be helpful. Viz:
query-front-pages-recent --numdays 7 |
sort --key=HN_priority | uniq
Web news is generally like this, making it hard to see yesterday's stories today. That's one reason my preferred news source is https://en.wikipedia.org/wiki/Portal:Current_events
