Global Creator Posting-Time Planner
Find the best hour to post when your audience is spread across timezones. Weight each region by its share of your followers — the tool ranks every hour of your day by how much of your audience is inside their prime engagement window at that moment.
How it works
For every hour of your local day (0–23), the tool figures out the corresponding UTC instant, then asks your browser's Intl API what the local hour is in each of your audience regions at that moment. Regions whose local hour falls inside the engagement window "count" — weighted by the audience share you gave them. Percentages are normalised so they always represent a share of your total tracked audience. The hour with the highest weighted score is your best slot; ties are broken by earliest-in-the-day.
How to use this tool
- Pick your own timezone — that's what the ranked hours below will be listed in.
- Add each region where a meaningful share of your followers live. You can find rough figures in YouTube Studio → Audience → Top countries, or Instagram Insights → Audience.
- Enter the audience share for each region. Any number works — the tool normalises so you don't have to make them add to 100.
- (Optional) Adjust the engagement window. Evenings (18–23) work for most creators, but news/business channels may prefer mornings.
- Read the ranked list — the top row is your best posting slot. Copy the results if you want to log them.
Frequently asked questions
Where do I find my audience-by-country data?
YouTube: Studio → Analytics → Audience → tab "Top countries". Instagram: Insights → Total audience → Top locations. TikTok: Analytics → Followers → Top territories. Rough percentages are enough — even ±5% doesn't move the ranking much.
Does the tool handle daylight saving time?
Yes. It runs the calculation against today's date via the IANA timezone database, so each region uses its current DST offset. The result is right for right now; re-check across a DST transition (mid-March or early November for most of the world).
Why does the tool suggest odd hours like 6 AM?
Because half your audience might be having dinner in Sydney or Tokyo while you're waking up. If a big share of your followers is on the other side of the world, the maths honestly leads to inconvenient posting hours. Use a scheduler (YouTube's built-in scheduler, Buffer, Later, etc.) so you don't have to be awake.
Why is the engagement window a range and not a single peak?
Real engagement peaks are messy — dinner-time in one country is post-work in another. A range captures "when people are online and receptive" better than a single hour. Tighter windows (e.g. 19–22) favour prime-time; wider windows (12–23) reward hitting more daytime hours.
What if my audience is very concentrated in one country?
Then the tool will basically show you the engagement window for that country — which is what you want. It shines when you're juggling 3+ regions and no single slot obviously wins.
