The best time to post is the day and hour when a specific account's audience is most likely to see and interact with its posts.
Why general answers mislead
Many articles publish a single "best time to post" chart per network. Those charts average across millions of accounts in different industries and time zones. Your audience is not the average.
What actually shapes your best time:
- Where your followers live.
- When they work, commute, and check their phones.
- How the network ranks posts. Mastodon and Bluesky default to chronological feeds, so timing matters more there; X and LinkedIn use ranking that extends a post's life.
- What else is being posted at that moment.
How to find yours
- Pick two or three candidate windows.
- Post comparable content in each for several weeks.
- Compare engagement rate by impressions, not raw likes.
- Treat small differences as noise.
An example
A developer tool finds that posts at 8:00 US Eastern do better on LinkedIn, while Bluesky posts do better mid-afternoon. It sets different defaults per network.
Why it matters for AI-agent publishing
An agent scheduling a week of posts needs a default time. If that default is a generic chart, every post lands at the same crowded hour.
SocialHandoff offers a best-time suggestion from your own per-post metrics, clearly labeled as a heuristic, since small samples produce confident-looking but weak answers. Agents can read it through get_insights. Compare network habits on the schedule pages.
