13.8% of a Day's Press Releases Land 8 to 9 a.m. Eastern

By the PR Gun Research desk. Updated November 1, 2026.

The busiest hour for press releases is 8 a.m. to 9 a.m. Eastern. In PR Gun's database, 13.78% of 97,043 press releases with a real send time, published May 7 to October 31, 2026 on five wires with reliable timestamps, went out in that one hour. The three hours from 8 a.m. to 11 a.m. Eastern carried 32.8%. A smaller second peak comes at 4 p.m. to 5 p.m. (5.84%), and the early afternoon is the quietest part of the working day.

Which hour gets the most press releases?

Everyone in PR has heard there's a morning pile-up. This study measures it. We used only wires whose timestamps include a real clock time. Those are PR Newswire, ACCESS Newswire, Business Wire, Newswire.com and Send2Press. We converted every time from UTC to Eastern time and dropped releases that carried only a date. That left 97,043 timed releases.

• In PR Gun's database, 13.78% of 97,043 timed press releases published May 7 to October 31, 2026 on five wires went out between 8 a.m. and 9 a.m. Eastern.
• The next busiest hours were 9 a.m. to 10 a.m. (10.33%) and 10 a.m. to 11 a.m. (8.68%).
• Together, 8 a.m. to 11 a.m. Eastern carried 32.8% of the day's releases.
• The 2 p.m. hour carried 4.02% and the 3 p.m. hour 3.45%, roughly a quarter to a third of the peak hour.

Why is there a second peak at 4 p.m.?

The 4 p.m. to 5 p.m. Eastern hour carried 5.84% of timed releases, more than any hour from 1 p.m. on. The NYSE core trading session ends at 4 p.m. Eastern, and public companies often release results and other market-moving news right after the close.

The release type data shows a late-day pattern too. Investor litigation notices, mostly from law firms, peaked later than anything else. Their busiest hour was 10 a.m. to 11 a.m., and 29.1% of 4,649 timed notices went out at 4 p.m. or later. Only 8.7% of 9,882 timed product launches did.

Business news is even more bunched than the average. For product launches, funding rounds, partnerships, acquisitions and executive appointments, the 8 a.m. hour alone carried 16.8% to 19.4% of releases, and 44.3% to 46.3% went out between 6 a.m. and 10 a.m.

Does every wire have the same peak?

No. Each wire's timed releases cover a different window in PR Gun's database, so read each row on its own.

PR Newswire, the largest, peaks at 8 a.m. with 14.6% of 79,338 timed releases published May 12 to October 31, 2026. Newswire.com peaks at the same hour but more sharply, with 21.44% of 3,135 releases. Business Wire peaks an hour later, at 9 a.m., with 18.73% of 2,777 releases published September 24 to October 18. Send2Press peaks at 7 a.m. with a third of its 479 releases.

ACCESS Newswire is the outlier. Its busiest hour is 5 a.m. to 6 a.m. Eastern, with 14.58% of 11,314 timed releases. That may reflect a scheduled pre-market release time on the service. We report it as measured.

Do releases go out on the hour?

Many look scheduled. Across the five timed wires, 23.0% of releases went out at exactly minute :00, and 39.0% at :00, :15, :30 or :45. If times were random, those four minutes would hold about 6.7% of releases.

On Send2Press, 55.1% went out at minute :00, and on Newswire.com 45.8%. On PR Newswire it was 20.0%. So the top of the hour is crowded, not just the 8 a.m. hour. A release scheduled for 8:00 lands with every other 8:00 release.

Why does everyone send at 8 a.m.?

Nobody planned the peak. It's the sum of many sensible choices. Public companies often release news before the NYSE opens at 9:30 a.m. Eastern. Everyone else reasons that reporters check email at the start of the day. Each choice makes sense alone. Together they produce the most crowded hour of the day.

A release in the 8 a.m. hour competes with three to four times as many releases as one at 2 p.m. or 3 p.m. That doesn't make the busy hour wrong. It does mean the advantage of being "first in the inbox" is shared with thousands of others.

What changed since the earlier study?

The first version of this page used an earlier sample of 134,126 releases studied May 7 to August 15, 2026. On the largest service, it found that one hour held 13.55% of 49,286 timestamped releases, the next 10.15% and the third 9.64%, with a second peak of 6.17%. Because the timezone of the stored times wasn't confirmed then, that version didn't name the clock hour.

For the 2026 rerun we confirmed that the stored times are UTC and converted them to Eastern time. The shape held. On PR Newswire alone, the 77,529 timed weekday releases peaked at 8 a.m. to 9 a.m. Eastern with 14.8%, followed by 9 a.m. (10.82%) and 10 a.m. (9.56%), with a later bump at 4 p.m. (6.21%). We can now say the peak is 8 a.m. Eastern.

What should you do about it?

• Don't default to 8:00 a.m. If your news isn't tied to the market open, consider 9:15 or 10:30. You still hit the morning, with fewer releases beside you.
• Avoid the exact top of the hour. Nearly a quarter of timed releases land at minute :00.
• Public companies have rules. Earnings and material news follow disclosure timing. Those releases belong at the open or the close.
• Match your reader's clock. A West Coast trade outlet starts its day three hours after New York. An 11 a.m. Eastern release is 8 a.m. Pacific.
• Test it. Two similar releases at different hours tell you more about your audience than any average.

By sender, a startup or small business with no market timing has the most freedom, so mid-morning is a fair default. An agency sending several client releases can spread them across the morning instead of stacking them at 8:00. A public company should follow its disclosure policy and exchange rules first, then think about crowding.

Frequently asked questions

What time do most press releases go out?

Between 8 a.m. and 9 a.m. Eastern. In PR Gun's database, 13.78% of 97,043 timed releases published May 7 to October 31, 2026 on five wires went out in that hour, and 32.8% between 8 a.m. and 11 a.m.

What is the least busy time to send a press release on a weekday?

Early afternoon. The 2 p.m. and 3 p.m. Eastern hours carried 4.02% and 3.45% of timed releases in PR Gun's 2026 data. Late evening is quieter still, but few reporters are working then.

Why do so many press releases go out at 4 p.m.?

The NYSE core session closes at 4 p.m. Eastern, and public companies and law firms often publish right after. The 4 p.m. hour carried 5.84% of timed releases, and 29.1% of investor litigation notices went out at 4 p.m. or later.

Should I schedule my press release on the hour?

It's better to avoid exactly :00. In PR Gun's 2026 data, 23.0% of timed releases went out at minute :00. A time like 9:20 puts you in the morning with less company.

Is 8 a.m. the best time to send a press release?

It's the most common time, which isn't the same thing. It suits market news. For other news, a mid-morning slot reaches the same reporters with fewer competing releases. See PR Gun's best time study for more.
