How to use these times
Treat the tables as a starting point, not a rule. A time that two or three studies share is a good first test; a time only one study names is an idea. Post at the candidate times for a few weeks, keep the content type steady, and compare reach and engagement in your own analytics before you settle on a schedule.
Where the studies disagree
The studies measure different things, so their answers differ. Sprout Social reports weekday windows around midday and afternoon and gives no weekend times. Buffer ranks the top three single hours for each day: mornings for Facebook and X, evenings for Instagram and LinkedIn. Hootsuite often reports early mornings for Facebook and LinkedIn.
Weekends split them most. Sprout Social says weekends are the weakest days on every network here, while Buffer names Saturday the best day for TikTok. On LinkedIn, Buffer ranks Monday the worst day, while Sprout Social and Hootsuite put Tuesday among the best. Hootsuite's overview and network pages also disagree in places, so this page uses its network pages where they exist and marks its X times as coming from the overview.
Your own audience beats any average
Every figure here is an average across many accounts in many countries. Your followers have their own habits, and the time zone that matters is theirs, not yours. PostBoost looks at your own accounts' results to suggest posting times and schedules posts to them, so you can move from study averages to your own data.
