Ad Account Time Zone: What It Controls and How to Change It on Meta, Google Ads and TikTok

Your ad account time zone decides how reports split data into days, how schedules are read, and on TikTok which dates your bill cycle uses. It is picked once, when the ad account is created, and none of the three big ad platforms lets you edit it in place. Meta can switch it for you, but only by closing the old ad account and creating a new one. Google Ads and TikTok Ads Manager ask you to create a new account.

This guide is based on the Meta Business Help Center, Google Ads Help and TikTok Ads Manager help articles on time zone and currency settings, as published in September 2026.

What the ad account time zone controls

Three things in that table are easy to get wrong.

The time zone does not decide where ads show. Google says the setting only affects how the account is administered, not the locations where ads can appear. Location targeting does that job.

Meta's scheduled delivery uses the audience's clock. Meta's article on ad set scheduling says your ad appears in your audience's time zone. If you want to compare how people respond in different time zones, Meta suggests a separate campaign for each one.

Google's billing pages ignore your choice. Google says that while you choose the account time zone, everything on the billing pages shows in Pacific Standard Time (PST). If finance reconciles spend by day, expect a small gap between reports and billing.

Meta: how to check and change the time zone

Meta's help article says the default time zone for new ad accounts is Pacific Standard Time (PST), so it is worth checking before you build the first campaign.

To change it, Meta gives these steps:

1. Go to Payment settings in Meta Ads Manager. You may be asked to re-enter your password.
2. In the Business info section, select Edit.
3. In Currency and time zone, pick the new time zone from the dropdown and select Save.
4. Select Continue.

What happens next is the important part. Meta states that changing the time zone closes the existing ad account, ads created in it stop running, and the closed account cannot be reactivated. A new ad account is created with the new time zone, and that is the one you run ads from.

Currency works through the same screen with the same effect. Meta's currency article says choosing a new currency and time zone creates a new ad account. The old one stays visible in the account dropdown but is closed, and ads that ran on it are billed in the old currency. It adds a few limits of its own:

• You can change currency once every 60 days, and only if there is no current balance.
• You need to be an admin of the ad account.
• If you pay by monthly invoicing, currency cannot be changed after the account is created.
• In some countries, such as Brazil, India and Poland, business country and currency must match. An account created with a country other than Brazil cannot later switch to Brazil, and one created in a currency other than BRL cannot later switch to BRL.

Before you switch on Meta, plan for the new account starting fresh: turn campaigns back on there, and keep the old account in mind when you pull historical reports.

Google Ads: the time zone is permanent

Google's help center is direct about this. Time zone changes are no longer supported in standard serving accounts. If you need to manage ads in a different time zone, you create a new account and set the time zone on the Billing page during setup.

Details worth knowing:

• Manager accounts are the exception. Google can reset a manager account's time zone only once, the request has to come from an Admin user, and the time zone can only move eastward, for example from GMT to India Standard Time (IST). After one reset, it cannot be changed again.
• Supported offsets. Time zones must be in full-hour or half-hour steps from GMT. The few local time zones offset by a quarter hour are not supported, so you have to pick a different one.
• History does not move. When campaigns are copied into a new account, historical data is not transferred. The new account tracks performance from launch.
• Copying campaigns. With a manager account, you can copy and paste campaigns into the new account. Without one, Google points to Google Ads Editor.

Currency on Google Ads follows the same rule: it is set at account creation, cannot be updated because it determines how you are billed, and a different currency means a new account.

TikTok Ads Manager: pick carefully at registration

TikTok's help article on time zones says you select the time zone when you create the account, and you cannot change it after registration. Its article on the information required for an ad account adds that time zone, region, business name and currency cannot be edited once the account exists, and points you to customer support for help with those changes.

According to TikTok, the time zone affects:

• the time your data is displayed on the platform, including reports,
• delivery settings, including start and end times,
• the bill cycle dates used for invoicing when calculating total ad costs.

Two more constraints from the same article. TikTok Ads Manager supports time zones that are a full or half hour ahead of or behind GMT/UTC, and it does not support quarter-hour offsets or daylight saving time for the account time zone.

To see what you picked: log in to TikTok Ads Manager, open Tools, then Account setup.

If you target markets in other time zones, TikTok's Time Zone Converter helps. TikTok says that since March 7, 2025 it lets you schedule by your local time zone or the target market's, converts the times automatically to the Business Center account time zone, and adjusts for regions that observe daylight saving time. When a campaign's start and end fall on different sides of a daylight saving change, TikTok shows a pop-up and you may need to move the end time by an hour.

How to choose the right time zone

The platforms' own descriptions point to one rule: pick the time zone your reporting day should close in, not the one your laptop happens to use.

• Match how the business reads a day. If finance or a client reports by calendar day in one market, use that market's time zone so daily numbers line up.
• One account per reporting clock. If you truly need two reporting days, for example for two regions, that is two ad accounts, not a setting you flip later.
• Check before the first campaign. Meta defaults to PST. Launching on the default and fixing it later means moving to a new ad account.
• Pick currency in the same step. On all three platforms, currency is fixed or changed together with the time zone, so decide both together.

For the rest of the setup order, see our Facebook ads account setup checklist and TikTok ads account setup.

Where AdBegin fits

Teams that run accounts across several markets often lose track of which ad account uses which time zone and currency. AdBegin is an ad workspace that keeps accounts, access and working environments organized as one set, so those account-level settings stay easy to see. It does not change any platform setting for you.

FAQ

Can I change my Facebook ad account time zone?

Yes, from Payment settings in Meta Ads Manager under Business info. But Meta closes the existing ad account, its ads stop, and it cannot be reactivated. A new ad account is created with the new time zone.

Can I change the time zone in Google Ads?

Not in a standard account. Google asks you to create a new account and set the time zone on the Billing page. A manager account can be reset once, eastward only, by request from an Admin user.

How do I change my TikTok ad account time zone?

You cannot edit it after registration. TikTok says time zone, region, business name and currency are fixed once the ad account is created, and points you to customer support for help with changes to those fields.

How do I check my ad account time zone?

On TikTok, go to Tools and then Account setup. On Meta, the time zone sits in the Currency and time zone part of Business info in Payment settings. On Google Ads, it is set on the Billing page when the account is created.

Does the ad account time zone change where my ads are shown?

No. Google says the time zone only affects account administration, not the locations where ads can show. Targeting is set separately.

The short version

Set the ad account time zone to the market whose calendar day you report on, and check it before the first campaign, since Meta starts new accounts on PST. Meta can change it, but only by closing the old ad account and creating a new one. Google Ads and TikTok Ads Manager lock it at creation, so a different time zone means a new account with no carried-over history. Choose currency at the same time, because all three platforms treat the two settings together.
