Ignore the generic charts. Your best time is when your own followers are online, and TikTok shows you that in analytics under follower activity. As a default before you have data, weekday evenings around 6 to 9pm and weekends work. But timing is the smallest lever here. TikTok keeps pushing a good video for days, so a strong hook matters far more than the minute you posted.
Timing is the smallest lever
TikTok pushes good videos for days, so the hook beats the clock every time.
Use your own analytics
Follower activity in your analytics tells you more than any generic chart.
Start with evenings
Weekday evenings and weekends are a fine default until you have your data.
Consistency wins
Posting daily at an okay time beats posting rarely at the perfect one.
