Weekday guidance
Monday
Test late morning as the week restarts, with a secondary early slot for commute or first-check behavior.
Tuesday
Prioritize the late-morning window; aggregate studies often show Tuesday as one of the stronger weekday options.
Wednesday
Keep late morning in the mix and compare it with lunch-hour posts for your category.
Thursday
Use lunch and early afternoon as the first test window, especially for B2B, education, or planning content.
Friday
Post earlier in the day before weekend attention fragments; avoid making Friday evening your only test.
Saturday
Weekend results vary more by niche. Try late morning or lunch, then let saves, comments, and reach decide.
Sunday
Late morning can work for planning, lifestyle, and creator content, but it should be validated against your own history.
A generic chart cannot know when your followers are awake, when your posts usually publish, or which formats your audience sees. Once an account has enough public posts, its own posting-cadence pattern is better evidence than a broad benchmark.
