Managing Facebook Ads effectively is not only about targeting, creatives, or bidding strategies. One of the most underestimated technical factors that directly impacts performance is the time zone setting in Facebook Ads Manager.Many advertisers realize something is wrong only after noticing unusual budget resets, daily reports that do not align with Google Analytics or CRM data, or campaigns spending aggressively during low-conversion hours. In most cases, the root cause is a mismatched ad account time zone.The critical point most marketers overlook is that Facebook does not allow changing the time zone of an existing ad account. Once an ad account is created, both time zone and currency are permanently locked. This setting controls when daily budgets reset, when automated rules trigger, and how performance data is aggregated.When the ad account time zone does not align with your primary market, several issues arise. Daily budgets may reset at inconvenient hours, campaigns may stop or start at the wrong times, and performance reports can become misleading. For global advertisers, these issues compound quickly, especially when running time-sensitive offers or automated scaling rules.If the account has not yet launched campaigns, the solution is simple: create a new ad account with the correct time zone from the start. However, for most advertisers who already have active campaigns, the only true fix is account migration. This process involves pausing campaigns, exporting historical data, securing audiences and pixels at the Business Manager level, creating a new ad account with correct settings, and rebuilding campaigns carefully.For advertisers who cannot migrate immediately, Facebook does offer limited workarounds. Using “viewer’s time zone” scheduling allows ads to display based on the user’s local time rather than the ad account’s time zone. Segmenting campaigns by region and using clear naming conventions can also reduce operational confusion. However, these methods are temporary solutions, not permanent fixes.Time zone configuration should be treated as foundational infrastructure, not a minor setting. Getting it right protects reporting accuracy, budget efficiency, and long-term scalability.#FacebookAds #MetaAds #PaidTraffic #MediaBuying #PerformanceMarketing👉 Full step-by-step guide: https://agrowth.io/blogs/facebook-ads/how-to-change-time-zone-in-facebook-ads-manager
