Best Time to Post on TikTok Sundays (Plus a Simple Test Plan)

Sunday is a weirdly high-leverage day on TikTok.

For some creators, Sunday is a “lazy scroll” day where morning posts pop off. For others, it’s an evening reset where people binge content before the week starts.

This guide shows you how to pick a smart starting point and then confirm it with your own data.

Quick Answer: Best Time to Post on TikTok Sundays

There isn’t one universal best time — but these benchmarks are useful hypotheses to test:

• Hootsuite’s Sunday benchmark (2025 data): 8 AM–12 PM (local time) https://blog.hootsuite.com/best-time-to-post-on-tiktok/
• Buffer’s Sunday benchmark (2026 data): 8 PM (with other strong slots at 5 PM and 4 PM) https://buffer.com/resources/best-time-to-post-on-tiktok/

Those recommendations don’t match — which is exactly why you should treat “best time” charts like a starting map, not a rule.

Why Sundays Behave Differently on TikTok

Sunday audiences often split into two groups:

• Morning scrollers: people easing into the day
• Evening planners: people decompressing or prepping for Monday

If your content is evergreen content (tutorials, explainers, FAQs), Sunday can be a great day because viewers have more patience to watch longer clips.

The 30-Minute Sunday Posting Window Audit

You can do this with the TikTok app + a notepad.

1) Check where your viewers live

Open your TikTok analytics and note the top countries/cities.

If you have a mixed audience, pick the dominant time zone to start testing. (You can expand later.)

2) Find your Sunday “Most active times”

If your account shows follower activity, use it to identify 2–3 peaks.

If you don’t see follower activity, use your own history:

• Look at your last 10–20 posts
• Write down day/time posted + rough performance
• Highlight anything that performed unusually well on Sunday

3) Choose 2 Sunday windows to test

Pick two windows that align with your audience and your schedule:

• Morning window: 8 AM–12 PM
• Evening window: 4 PM–9 PM

Don’t over-optimize to a single minute. Stick to ranges.

A Simple Sunday Test Plan (2 Weeks)

For the next 2 weeks, post the same style of content on Sundays (same niche, similar length, similar hook structure), alternating between your two windows.

Track one primary metric:

• Watch time (best default)
• Or saves/shares (great for educational evergreen content)

After two Sundays per window, you’ll usually see a pattern.

Make Sunday Easier With Evergreen Content + Scheduling

Sunday is the day creators most often skip — not because it’s bad for reach, but because they want their weekend back.

That’s where simple systems help:

• Batch-create 3–5 evergreen posts
• Put them into a recurring rotation
• Schedule them to publish while you’re offline

With https://www.brandghost.ai, you can plan and schedule your TikTok content (and cross-posting variations) so Sunday reach doesn’t require Sunday work.

FAQ

Should I post on TikTok on Sunday?

If your audience is active on weekends, Sunday can be a strong day — especially for evergreen content. Test it rather than assuming.

Why do some guides say Sunday morning and others say Sunday evening?

Different datasets, audiences, and time zone assumptions can lead to different “best times.” Use benchmarks to choose test windows, then decide using your own analytics.

What if I can only post once on Sundays?

Pick one window (morning or evening) and run a 4-week test. Consistency matters more than perfect timing.
