Key takeaways
- The 2026 TikTok studies conflict: Sprout Social favours weekday afternoons (2–6pm), Buffer’s 7.1M-post data favours Sunday and Monday slots and evenings.
- Published studies show the general pattern, but your own audience’s activity is the more reliable signal — test and compare.
Best time to post on TikTok: two studies, two different answers
- Sprout Social (31 Mar 2026): best days Monday to Friday; best times Tuesday to Friday 2–6pm; weekends worst
- Buffer (updated 14 Sep 2026; 7.1 million posts): top slots Sunday 9am, Monday 1pm and Sunday 1pm; Saturday the best day; evenings 6–11pm strongest and 12–5pm the lowest
- What Sprout Social calls its weakest days include Buffer’s strongest (Saturday), so the two cannot both be followed
How to apply this
Do not try to split the difference. Run one weekday-afternoon window and one evening or weekend window against your own audience for several weeks, and keep the winner.
Why timing is a secondary lever
Content quality and consistency matter more than the exact hour, and both studies say to test against your own audience.

FAQ
- What is the best time to post on TikTok?
- The two 2026 studies conflict: Sprout Social favours Tuesday to Friday 2–6pm, while Buffer (7.1M posts) favours Sunday 9am, Monday 1pm and evenings.
- Why do TikTok best-time studies disagree so much?
- Their samples, periods and engagement definitions differ, and neither published page explains the gap, so your own account’s data is the tiebreaker.
- Does posting time matter as much on TikTok as other platforms?
- Buffer’s own study says content quality is the most important factor; timing is a secondary lever to test.
