The Best Day and Hour to Publish a Press Release — Data From 150,216 Releases

We bucketed 150,216 press releases by day and hour. The data on the best time to publish — and why the loudest slot on the wire may be the worst choice.

Ask when to send a press release and you'll get the same folklore everywhere: Tuesday morning, never on a Friday, avoid the holidays. Almost none of it arrives with data attached — most of it traces back to a blog post citing an older blog post citing nobody.

We're in a position to do better. PPN World monitors 1200+ press release feeds from 80+ newswires across 190+ countries, and every release lands in our archive with the timestamp the wire published it under. So we took four complete UTC weeks — July 11 to August 7, 2026, all 150,216 releases — and bucketed them by day of the week and hour of the day.

Here is what the wire actually does. And, just as important, here is what these numbers do and don't tell you about when you should publish.

The shape of a week on the wire#

Across the window, the wire averaged 5,365 releases per day. The average hides the real structure:

Four readings:

• Tuesday through Thursday is a plateau, not a peak. Thursday nominally tops the week at 7,575, but Tuesday (7,538) and Wednesday (7,437) sit within 2% of it. Those three days carry roughly 60% of the entire week's releases.
• A single Tuesday outweighs the whole weekend almost three to one. Tuesday's 7,538 releases against Saturday plus Sunday combined (2,696) — the industry has clearly absorbed the "publish midweek" advice, en masse.
• Monday runs about 20% below Tuesday. The week ramps up rather than starting at full volume — releases drafted Monday go out Tuesday.
• The fabled Friday news dump happens on a busy day. Friday's 6,258 is only about 17% below Thursday. If you're burying news on Friday, you're burying it in a crowd four times the size of Saturday's.

The shape of a weekday, hour by hour#

Hour-of-day totals, weekdays only, summed over the last five weekdays of the window (Eastern column is summer time, UTC−4):

The structure:

• The loudest block is 12:00–14:00 UTC — 8 to 10 a.m. Eastern, the pre-market and market-open window. The 12:00 hour alone (2,797) is about 8% of a weekday's releases; the three-hour block carries more than a fifth of the day.
• A secondary European rise starts at 07:00 UTC. At 2,237, it's the second-busiest single hour of the day — 9 a.m. in Central Europe, the continent's own morning push, hours before New York wakes up.
• The 20:00 UTC bump (1,415) is 4 p.m. Eastern — the after-the-close slot where U.S. earnings and market-sensitive announcements land.
• The quietest weekday stretch is 21:00–23:59 UTC. The 23:00 hour (433) carries roughly a sixth of the noon hour's volume.

What this data measures — and what it doesn't#

Now the honest part, which the "best time to send" articles skip: these numbers measure supply, not pickup. They tell you when releases go out. They tell you nothing about which releases get read, covered, or traded on — our archive records publication, not outcomes.

That distinction cuts both ways. The Tuesday–Thursday, 12:00–14:00 UTC peak exists because decades of PR advice told everyone the same thing, and everyone complied. Which means publishing at Tuesday 13:00 UTC — the textbook "best time" — drops your headline into the densest list of the entire week, in every inbox, monitoring tool, and feed your audience uses. The advice is self-defeating at scale: the best-known slot is, by construction, the most crowded one.

The same tables suggest a contrarian read. A Tuesday release at 15:00–16:00 UTC (11 a.m. to noon Eastern) still reaches the full weekday audience at their desks — but against roughly 40% fewer simultaneous releases than the midday peak. You give up nothing measurable in audience and shed close to half the noise.

The weekend is the extreme version of the trade: a Sunday release competes with almost nothing (1,242 for the whole day) — and is read by almost no one, surfacing Monday morning at the bottom of a 6,000-release pile.

So when should you publish?#

What the data supports, by goal:

One more timing tool the tables can't capture: if your announcement needs to land at a precise minute — coordinated coverage, an exchange filing, a product launch — that's not a scheduling question, it's an embargo question. We wrote a full guide to press release embargoes covering when they bind and when they backfire.

Methodology#

• Source: the PPN World archive — every release ingested from all 1200+ monitored feeds across 80+ newswires and official sources.
• Window: four complete UTC weeks ending August 7, 2026 (July 11 – August 7). 150,216 releases total.
• Timestamps: as published by the wires themselves, bucketed in UTC. The hour-of-day table covers weekdays only, summed over the last five weekdays of the window.
• Limits: this is supply-side data. Volume is not coverage; nothing here claims that publishing in a given slot changes pickup. Percentages and ratios in this article are derived directly from the tables above — no other figures were used.

We publish refreshed wire-volume numbers monthly on our State of the Wire page.

See your slot before you commit to it#

The cheapest way to sanity-check a publication time is to watch the wire at that time. Open the live feed on a Tuesday at 13:00 UTC and again at 15:30, and the difference in what your headline would be competing with is not subtle. And if you're on the issuing side of the wire, our sister product PPN Source handles distribution — same company, other direction.

PPN World early-access plans start at $39/month (regular $99), with a 72-hour free trial and no card required.

Frequently asked questions#

What is the best day to send a press release?

Any of Tuesday, Wednesday, or Thursday — they form a plateau within 2% of each other in our data, with Thursday nominally on top. The differences inside the plateau are noise; the difference between the plateau and the weekend is a factor of five.

What is the best hour to send a press release?

It depends on what you're optimizing. The industry's habit is 12:00–14:00 UTC (8–10 a.m. Eastern), which is also the most crowded window of the week. If your news isn't bound to market hours, 15:00–16:00 UTC keeps the weekday audience with roughly 40% less simultaneous volume.

Does publishing at a quiet hour get more coverage?

Unknown — honestly, by anyone. Our data measures when releases are published, not how they perform. What a quieter slot demonstrably changes is the size of the list your headline appears in; whether that converts to coverage depends on the release itself.
