Best time to post on Hacker News, day by day
Monday
Peak activity starts: 9 to 10 a.m. ET.
Tuesday
Part of the strongest window for technical posts.
Wednesday
Midweek US morning is the default for essays and product write-ups.
Thursday
Still in the prime window.
Friday
Traffic drops in the afternoon; post in the morning or wait.
Saturday
Weekend patterns favour long reads over discovery.
Sunday
10 a.m. ET is a second-best launch option with lower competition; midnight to 1 a.m. Pacific is a contrarian low-competition window for niche posts.
How Hacker News ranking uses time
The front page ranks stories by votes and age, plus flags, anti-abuse software, overheating, site weighting and moderator action. Timing alone will never guarantee the front page.
Two goals pull in different directions. More readers online means US weekday mornings. Fewer competing submissions means quieter windows, such as Sunday night Pacific, where a strong post can still get an early push. A Show HN usually needs early upvotes within its first hour to reach the front page.
Timing by submission type
Regular link post
Tuesday to Thursday, 14:00 to 17:00 UTC for technical essays, product write-ups and serious links.

Monday to Thursday, 9 to 10 a.m. ET; Sunday 10 a.m. ET as the second option. Keep the title under 80 characters.
Niche or unusual posts
Test Sunday night Pacific, when fewer people submit.
Side projects and long reads
Weekends are viable for curiosity-driven posts.

Research, not a prediction
Hacker News timing advice is all over the place because studies answer different questions: best chance per post versus biggest total audience. An older large analysis found activity peaks around 12 p.m. Eastern but that submission time alone did not strongly decide which posts went viral.
Treat the windows as heuristics. Etiquette and the post itself count more than timing.
Where the data comes from
Windows come from a 2026 Hacker News timing analysis (including a 365-day top-stories heatmap and a 23,000-post study) and a 2026 Show HN launch guide.
