Evenings, after school and work
Buffer's 7.1 million TikTok posts do best from 18:00 to 23:00 and worst from 12:00 to 17:00. Metricool's peak is 18:00 to 20:00 on Sunday evening.
Hootsuite and Sprout disagree: Hootsuite names Thursday mornings, Sprout weekday afternoons from 14:00. A morning test is cheap, but the evening has the most studies behind it.
The weekend question
Buffer ranks Saturday as TikTok's best day and Sunday at 9:00 as its best slot. Metricool also picks Sunday. Sprout ranks weekends weakest, and Metricool calls Saturday the quietest day.
With that split, post on Sunday and on one weekday evening, then let your own views decide between them.
The first day decides more than the minute
TikTok shows a new video to a small group first and widens the audience if they watch. Buffer finds the first hour of engagement shapes how far it travels, and Hootsuite notes a video can take about 24 hours to be fully pushed out. Judge a post after a day, not after an hour.

How often to post on TikTok
Buffer's study of 11.4 million TikTok posts from over 150,000 accounts found the biggest lift comes from posting 2 to 5 times a week: up to 17% more views per post than posting once. TikTok's own advice, as Hootsuite reports it, is 1 to 4 posts a day, which few small teams can keep up.
Sources and method
Every window in this guide is what a study's own page says, read on the date beside it. Where a study's overview and its page for one platform disagree, we used the platform page, which is newer and narrower.
The charts count how many of the studies name each hour or day. They show where the studies agree, not how much engagement an hour gets: no study publishes its raw numbers.
