We Analyzed 34,095 Reddit Posts Across 50 Subreddits. Here's When Timing Actually Matters.

Everyone repeats the same Reddit timing advice: post on weekday mornings, US Eastern Time, and avoid the weekend. Almost nobody shows their data. So we pulled our own: 34,095 posts from the public listings of 50 subreddits, crawled in July 2026, and measured how posting hour and weekday actually relate to post scores.

In our July 2026 analysis of 34,095 Reddit posts across 50 subreddits, posting hour swung median post scores by up to 6.8x in large communities but under 2x in the very biggest and smallest ones, and Friday ranked among the bottom three days in every size tier.

The short version: timing is real, but it is not one dial. It matters enormously in some communities and barely at all in others.

Key takeaways

• Posting hour matters most in large subreddits (3M to 22M subscribers), where median scores of top posts swing 6.8x between the best and worst hours.
• In mega subreddits (16M+) and small subreddits (under a few hundred thousand active scale), the hour-to-hour swing is under 2x. Content and community fit dominate.
• The weak zone is consistent: 8:00 to 10:00 UTC (4 to 6 AM Eastern) produces the lowest medians in large subs by a wide margin.
• There is no universal best day. Sunday wins in mega and mid subs, Thursday wins in large subs, Tuesday edges out small subs.
• Friday is the closest thing to a universal answer: bottom three days in all four size tiers, dead last in mega subs.
• All findings come from Reddit's public top listings, which oversample successful posts. Treat them as patterns among winners, not guarantees.

What exactly did we analyze?

We crawled 34,095 posts from the public listings of 50 subreddits in July 2026 and grouped them into four subscriber-size tiers. Score-by-time analysis uses the 25,563 posts from top-of-year and top-of-month listings. A separate 385-post snapshot of the new listings gives us a view of posting competition by hour.

Methodology in full:

• Sample: 34,095 posts across 50 subreddits, collected July 2026 from Reddit's public listings. Post creation dates span July 2023 to July 2026.
• Listing mix: 14,807 posts from top-of-year listings, 10,756 from top-of-month, 8,147 from hot, and 385 from new.
• Time analysis: hourly and weekday score tables are built from the 25,563 top-of-year and top-of-month posts, using each post's creation time in UTC.
• Competition analysis: built from the 385 new-listing posts, a point-in-time snapshot of what was being submitted.
• Medians, not averages: Reddit scores are heavily skewed by a few viral outliers, so we report median scores throughout.

The four size tiers:

Tiers were assigned per subreddit, so the subscriber ranges overlap slightly at the edges. That is a property of the sample, not a typo, and we kept it visible rather than reshuffling communities to make the bands look cleaner.

Does the hour you post actually matter?

Yes, but how much depends heavily on subreddit size. In our data, the gap between the best and worst posting hour is 6.8x in large subreddits and roughly 5x in mid subreddits, yet only 1.9x in mega subreddits and 1.8x in small ones. Timing is a mid-size-community lever, not a universal one.

Here is the swing per tier, measured as the ratio between the highest and lowest hourly median score among top-listing posts:

*The mid-tier worst hour (5:00 UTC, median 19) looks anomalous against its neighbors, which sit between 137 and 145. Using the second-worst hour instead (10:00 UTC, median 34), the mid-tier swing is still 5.1x. We flag this rather than hide it; a single scheduling quirk in one or two communities can produce a dip like that, and we cannot rule that out from this data.

The practical reading: if you post in communities in the roughly 300K to 20M subscriber range, your submission hour is one of the biggest levers you control. If you post in the very biggest communities or in small niche ones, timing still helps at the margins but it will not rescue or ruin a post on its own.

What are the strongest and weakest hours in each tier?

The strong window across tiers clusters in the late UTC afternoon through midnight, which maps to US waking hours. The weak zone clusters between roughly 5:00 and 11:00 UTC, the overnight and pre-dawn hours for US users, and it is deepest in large subreddits.

Per tier, from the top-listing data:

• Mega: 0:00 UTC leads at a 24,593 median (8 PM Eastern), with a secondary block from 19:00 to 21:00 UTC at 19,439 to 19,928. The floor is 11:00 UTC at 13,180.5. Even the worst hour is more than half the best, which is why we call mega timing flat.
• Large: 20:00 UTC leads at 335 (4 PM Eastern), followed by 22:00 at 301, 12:00 at 286, and 5:00 at 283. The collapse is stark at 8:00 to 10:00 UTC: medians of 60.5, 49, and 49.5, against an evening block routinely above 220.
• Mid: the best hours are 23:00 UTC at 173, 0:00 at 171, and 17:00 at 170. The weakest stretch is 5:00 to 10:00 UTC, with the caveat above.
• Small: everything lives between 9 and 16. The best hour (21:00 UTC, median 16) and the worst (6:00 UTC, median 9) are close enough that we would not build a strategy on it.

If you want one memorable rule from the hour data, it is this: in large subreddits, 4 to 6 AM Eastern is where posts go to disappear.

Is there a universal best day to post on Reddit?

No. In our data the best day changes with subreddit size: Sunday wins in mega and mid subreddits, Thursday wins in large ones, and Tuesday narrowly leads in small ones. The only pattern that holds everywhere is negative: Friday sits in the bottom three days in all four tiers.

The full weekday table, median score of top-listing posts by the day they were submitted:

Three things jump out:

1. Friday is the weak spot everywhere. Dead last in mega subs (14,371, about 18% below Sunday), second-worst in large and mid, and tied for the bottom in small. If you can move a post off Friday, our data says do it.
2. The weekend advice is wrong for half of Reddit. Sunday is the single best day in mega and mid subreddits. The "weekends are dead" rule only holds in the large tier, where Saturday (154) and Friday (175) are the two worst days and Thursday (267) leads by 73% over Saturday.
3. Day effects are smaller than hour effects. The biggest weekday gap in any tier is 1.7x (large, Thursday vs Saturday). Compare that to the 6.8x hourly swing in the same tier. If you can only optimize one thing, optimize the hour.

When is posting competition lowest?

Our 385-post snapshot of the new listings shows submission volume in large subreddits peaking between 21:00 and 1:00 UTC, while several daytime UTC hours saw almost no new submissions. But at this sample size the competition data is directional at best, and we treat it that way.

What the snapshot shows:

• Large tier (114 new posts): the busiest hours were 22:00 UTC with 17 posts, 23:00 with 15, and 21:00 and 1:00 with 10 each. At the other end, 20:00 UTC had a single observed post, and 6:00 and 11:00 had none.
• Mega tier (137 posts): busiest at 14:00 UTC (14 posts) and 18:00 (12); quietest at 6:00 (1 post).
• Mid tier (110 posts): busiest at 15:00 and 20:00 UTC (11 each).
• Small tier: only 24 new posts observed in total, too few to read anything into.

One curiosity worth naming, with a heavy caveat: in large subreddits, 20:00 UTC produced both the highest median score among top posts (335) and the lowest observed submission volume (1 post in our snapshot). High-performing hour, quiet queue. If that pattern held up under a bigger competition sample it would be a genuine arbitrage window. From one snapshot, it is a hypothesis to test, not a fact to bank on.

Why is timing so flat in mega and small subreddits?

Our reading, stated as interpretation rather than proof: mega subreddits have audiences so large and globally spread that someone is always scrolling, which smooths out the clock. Small subreddits sit at the opposite end, where the score ceiling is low at every hour, so community fit and content quality dwarf timing.

The mega floor supports the first half: the worst mega hour still posts a 13,180.5 median, a number no other tier touches at its best. There is no dead hour in a community with tens of millions of subscribers.

The small-tier band supports the second half: medians from 9 to 16 across all 24 hours means a perfectly timed post and a badly timed post land within a few upvotes of each other. In those communities, the question is not when you post. It is whether the community wants what you posted at all. Before worrying about the clock in a small subreddit, check its posting rules and activity with our free subreddit stats checker and see who actually drives it with the active posters tool.

The large tier is where both forces are live: the audience is big enough that a well-timed post can catch a huge wave, but concentrated enough (heavily US waking hours in our data) that the wave has a schedule. That is why the 6.8x swing lives there.

What are the limits of this data?

The biggest limitation is survivorship: top-of-year and top-of-month listings only contain posts that already succeeded, so our hourly and weekday medians describe when winning posts were submitted and how high they scored, not the success rate of submitting at each hour. We are honest about that because most timing studies are not.

The full caveat list:

• Survivorship bias. A median of 49 at 9:00 UTC in large subs does not mean your post will score 49 at that hour. It means even the posts that made the top listings scored dramatically lower when submitted then, which is itself a strong signal about the ceiling at that hour, but a different claim.
• Correlation, not causation. Hour of submission correlates with which communities and which content types post at that hour. We did not control for content.
• Aggregates hide per-subreddit reality. These are tier-level patterns across 50 communities. Any single subreddit can and does deviate. Check your specific target with our free best time to post tool before scheduling anything.
• The competition snapshot is small. 385 posts across 50 subreddits is a single point-in-time view of the new queue. We report it as directional only.
• Anomalies exist and we kept them. The 5:00 UTC mid-tier dip and the zero-post hours in the new-listing snapshot are in the data as collected. We would rather show you a wrinkle than iron it out.

How should you actually use these numbers?

Match your effort to your tier: in large and mid subreddits, schedule deliberately into the 17:00 to 0:00 UTC block and stay away from Friday and the 5:00 to 10:00 UTC trough; in mega and small subreddits, spend that same energy on the content itself. Then make sure the first hour goes well, because timing only buys you an audience, not their upvotes.

A simple playbook from the data:

1. Size your target subreddit and find which tier behavior applies. Subscriber count is on every subreddit's sidebar, or run it through our free subreddit stats checker.
2. Pull the community's own pattern. Tier averages are the starting point; the specific subreddit's rhythm wins. Our free best time to post tool surfaces a community's most active hours directly.
3. Default to the strong block if you have nothing better: 17:00 to 0:00 UTC (1 to 8 PM Eastern), on any day except Friday. In large subs, treat 8:00 to 10:00 UTC as a no-post zone.
4. Protect the first hour. Timing determines how many people can see your post early. What they do next decides everything, because Reddit's ranking rewards early velocity, which we break down in our Reddit algorithm guide. If a post is business-critical and landing in its window with zero early momentum, that first hour is exactly what our Reddit upvote service exists for: real accounts adding the early signal that a well-timed post needs to catch its wave.
5. Log and iterate. Two or three posts per window per subreddit will tell you more about that community than any aggregate study, ours included. Pair this with our practical best time to post guide for window tables by category, and the scheduling guide for how to actually hit those windows.

FAQ

Does posting time matter on Reddit?

Yes, but the size of the effect depends on the community. In our 34,095-post analysis, posting hour swung median scores 6.8x in large subreddits (3M to 22M subscribers) and about 5x in mid-size ones, but under 2x in the very biggest and the smallest communities.

What is the worst day to post on Reddit?

Friday, as consistently as our data shows anything. It ranked in the bottom three days in all four subreddit size tiers we measured, and dead last in mega subreddits, where Friday's median score ran about 18% below Sunday's. No other day was weak across every tier.

Is it better to post on Reddit on weekends or weekdays?

It depends on community size. In our data, Sunday was the best day in both mega and mid-size subreddits, so weekends are far from dead. But in large subreddits (3M to 22M subscribers), Saturday and Friday were the two worst days and Thursday was the strongest.

What time is Reddit most active?

Our top-listing data points to US waking hours: the strongest medians cluster from 17:00 to 0:00 UTC (1 to 8 PM Eastern), and the weakest sit between 5:00 and 11:00 UTC. Individual subreddits vary a lot, so check your specific community before scheduling around the aggregate.

Where does this data come from?

From our own July 2026 crawl of Reddit's public listings: 34,095 posts across 50 subreddits, spanning post dates from July 2023 to July 2026. Score-by-time findings use the 25,563 top-of-year and top-of-month posts; the competition snapshot uses 385 new-listing posts.
