Bluesky, day by dayWeekday evenings, about 6 to 9 PM in your audience's local time, is where the studies overlap most. Only 3 studies with their own Bluesky data exist, and they disagree on the day. Treat the map as a starting point.
Checked on against 7 sources.
Only 3 studies with their own Bluesky data exist, and they disagree. Buffer's 3 million posts favor weekends, SocialPilot's 1 million favor weekday mornings, and Postpone favors weekday late mornings. The slot they share most is the weekday evening, about 6 to 9 PM. Overnight, midnight to 6 AM, is the time to avoid. On the combined map Friday edges ahead by a small margin, though no study calls it the best day.
Bluesky itself gives no clock time. Its Following feed shows posts by people you follow "in the order they posted them", so a post lands in front of whoever is scrolling then. A fourth study, BskySuite's 27,755 posts, found that inside a single account the hour made no measurable difference. Use the map as a start, then test it on your own posts.
You can now keep your posts from being shown to non-followers in the Discover feed. Bluesky: "Sometimes you're just posting for your followers." Source
Bluesky said "The Discover feed has come a long way, but there's more to do" and that posters should find the right audience more easily. Source
Bluesky described Following as "posts by people you follow, in the order they posted them" and let users make another feed their home feed. Source
Buffer and Postpone use local time. If most followers live in New York, plan in Eastern Time, wherever you are.
6 to 9 PM is the one window two of the three studies share on most days. Put your most important posts there first.
Buffer's top slot is Saturday at 5 PM, while Postpone found weekends about 24% weaker than Wednesday. Your audience breaks the tie.
The Following feed is newest first. A post at 3 AM sits under hours of newer posts by the time most followers open the app.
Post similar content at two times and compare likes, reposts and replies. One week is too noisy to call.
BskySuite found no hourly effect inside the same account. A steady topic and replies to people matter more than the exact hour.

ThreadsBest time to post on ThreadsBlueskyBest time to post on BlueskyThis pageOnly three studies publish Bluesky timing data from their own sample with a stated size or method: Buffer, SocialPilot and Postpone, published August to October 2026. Each gets one vote per day and three-hour block: plus one when it names the block as a best time, minus one when it names it, or the whole day, as one to avoid. A window votes for every block it overlaps. The votes are scaled from 0 to 100, so the map shows where the studies agree, not an engagement rate. With so few studies, treat it as a rough guide. BskySuite names no best time, so it casts no votes; Metricool, Hopper HQ, RecurPost and Social Champ give times without a described dataset and are left out.
