About Daylight Saving Time and Scheduling LIVE Shopping Ads

Last updated: March 2025

To create LIVE Shopping Ads on TikTok Ads Manager, you will need to schedule when the ads start delivering. We recommend you schedule LIVE Shopping Ads so they start running and end at the same time as the LIVE video broadcast.


Live Shopping Ads and Universal Timecode (UTC)

When you schedule LIVE Shopping Ads, you will select the ad delivery start and end times according to your account's coordinated universal timecode (UTC). Since UTC does not support daylight saving time, you may need to adjust the ad delivery schedule if the LIVE video is being broadcast from a location that observes Daylight Savings Time.

To schedule LIVE Shopping Ads to match the start time of the LIVE video, you will need:

  • The LIVE video's start and end time.

  • The current UTC time zone of the LIVE video's broadcast location.

Note: This UTC time zone will change if the location observes Daylight Savings Time. For example, if California observes Daylight Savings Time, the time there is UTC-8, but during Daylight Savings Time, it changes to UTC-7.

  • The ad account's UTC time zone, which will not adjust per DST. For example, an ad account created in California will use UTC-8 time zone for the entire year.

To calculate when to schedule your LIVE Shopping Ads:

  1. Determine the difference between the current UTC time zone of the LIVE video's broadcast location and your ad account's UTC time zone.

  2. Add the difference to your LIVE videos start and end time.


Live Shopping Ads and UTC Time Zone

See the table below to see how to schedule LIVE Shopping Ads delivery when:

  • The LIVE video is being broadcast from the same UTC time zone as the ad account.

  • The LIVE video's broadcast UTC time zone is different from the ad account.

  • The LIVE video's broadcast UTC time zone observes DST.

Timezone Converter for LIVE Shopping Ads

As of March 6, 2025, TikTok Ads Manager now includes an embedded Timezone Converter to simplify scheduling and reduce manual adjustments. You can schedule LIVE Shopping Ads based on your local timezone or the target market's timezone, with the scheduled time automatically converted to the Business Center account timezone for ad delivery.


If a region observes Daylight Savings Time, the converter will account for the shift, so you don't need to make manual corrections. If the start and end times fall under different timezones due to the duration of the campaign, you may need to adjust the end time by 1 hour forward or backward to ensure accurate delivery.
