> Quick answer: Select target countries at the ad group level, use TikTok's Timezone Converter to set delivery in each market's local time, and add dayparting if you want to narrow delivery to specific hours. TikTok auto-converts everything to your Business Center timezone for reporting.
Running ads across multiple countries means your 9am must land at the right moment in every market. TikTok Ads Manager gives you location targeting, timezone scheduling, and dayparting to handle that. Here's exactly how to set it up.
What Does Scheduling Ads by Country Mean?
Scheduling by country is really two separate settings working together.
Location targeting and timezone considerations
Location targeting controls who sees your ads. Timezone scheduling controls when they see them. Your Business Center has one fixed timezone that cannot change after setup. But your target audiences may be spread across a dozen different ones. Getting both settings right is what makes country-level scheduling work.
Why schedule differently for global audiences
A 9am flash sale hits differently in New York than in Sydney. Running ads at the wrong hour burns budget on audiences that are asleep or offline. Aligning delivery with peak hours in each market means more impressions, more clicks, and more efficient spend.
Location Targeting: Choose Your Countries and Regions
Location targeting is where you define which markets receive your ads.
How to select countries, regions, states, and cities
Per TikTok's Business Help Center on location targeting, TikTok Ads Manager supports targeting by country, region, state, province, metro area, city, and zip code. You configure location at the ad group level. You can add multiple countries to a single ad group or split markets across separate ad groups for tighter creative and budget control.
Available targeting options by account region
Not all markets are available to every advertiser. Per TikTok Ads Manager's placements and available locations documentation, select your registered country from the dropdown to see the markets your account can reach. If a country isn't listed, TikTok may not operate in that market or cannot deliver ads there yet.
Schedule by Timezone: Local vs. Target Market
Timezone scheduling determines when your ads actually go live in each country.
Understanding the Timezone Converter feature
TikTok Ads Manager includes a Timezone Converter tool. It lets you schedule delivery in any timezone, not only your account default. Per TikTok's timezone documentation, the time you select is automatically converted to your Business Center account timezone for consistent delivery, reporting, and budgeting.
Selecting local timezone or target market timezone
When setting your campaign schedule, pick a timezone from the dropdown menu. You can choose your own local timezone or your target market's timezone. The practical difference is simple. whose clock governs when the ad goes live.
How TikTok converts to your Business Center timezone
Whatever timezone you select, TikTok converts it internally before delivery. All reporting, budget pacing, and ad delivery run against your Business Center timezone. You schedule in the market's clock. TikTok does the offset math so you don't have to.
Set Your Campaign Start and End Dates and Times
Dates and times are set during campaign creation.
Creating a campaign with scheduled dates
TikTok Ads Manager's step-by-step guide identifies budget and schedule as Step 5 of campaign creation. Set a start date, end date, and delivery time at this step. The guide specifically flags timezone verification here because your Business Center timezone cannot be changed after account setup. Confirm it before you publish.
Accounting for daylight saving time differences
The US, UK, and parts of Australia all observe daylight saving time. Per TikTok's timezone documentation, the system automatically accounts for DST in regions that observe it. Even so, double-check scheduled end dates that cross a DST transition. A one-hour shift can quietly push delivery outside your intended window.
Use Dayparting to Run Ads at Specific Hours
Dayparting gives you hour-level control on top of your date range.
What dayparting is and when to use it
Dayparting lets you restrict ads to specific hours within a day. Use it when your audience is most active in a narrow window, when you want ads aligned with store or business hours in a target market, or when prior data shows off-peak hours waste spend.
Setting specific hours within your target timezone
Set your dayparting hours using the Timezone Converter. Select the timezone your target market uses. TikTok automatically converts those hours to your Business Center timezone for delivery. Your 8am to 10am window in Tokyo resolves to the correct UTC offset without any manual calculation on your end.
Putting It All Together: A Multi-Country Campaign Example
Here's how the settings combine in practice.
Scenario: scheduling a campaign across US, UK, and Australia
Say you want a sale ad running from 9am to noon in each market's local time. Create three ad groups: one targeting the US, one targeting the UK, one targeting Australia. Set location targeting per ad group. Open the Timezone Converter and set 9am to noon in the respective timezone for each group. Use dayparting to lock those hours if you want to prevent delivery outside that window.
How timezone conversion handles the scheduling
Each ad group runs in its own local window. TikTok converts all three schedules to your Business Center timezone internally and coordinates delivery. You get unified reporting in one timezone. Each audience sees your ad at the right local hour. No manual offset spreadsheet required.
Common Scheduling Mistakes to Avoid
Two errors trip up most multi-country campaigns.
Forgetting to account for daylight saving time
DST moves clocks by one hour in dozens of markets. That one-hour shift can slide your carefully planned 9am slot to 8am or 10am without any alert from the platform. Log the DST transition dates for your key target markets. Check campaigns that are live around those dates and adjust if delivery drifts.
Confusing account timezone with delivery timezone
Your Business Center timezone is locked at account creation. It cannot be changed. The Timezone Converter adjusts when your ads deliver, but all performance reporting reflects your account timezone. Before pulling data, confirm which clock the numbers are reading. Mixing the two up leads to misread campaign results and bad optimization calls.

Frequently Asked Questions
Can I target different countries in the same TikTok ad group?
Yes. TikTok Ads Manager lets you add multiple countries to a single ad group. If you want separate budgets, creatives, or timezone schedules per market, split each country into its own ad group instead.
What happens if I don't use the Timezone Converter?
Your campaign will schedule in your Business Center account timezone by default. If your target market is in a different timezone, that means your ads may run at the wrong local hour for your audience.
Can I change my Business Center timezone after my account is set up?
No. Per TikTok Ads Manager documentation, your account timezone is fixed at account creation and cannot be changed. Verify it carefully before you create your first campaign.
Does TikTok automatically adjust for daylight saving time?
Yes. TikTok's timezone system automatically accounts for daylight saving time in regions that observe it. Still, check campaigns with end dates that cross a DST transition to confirm delivery stays in your intended window.
