1487852 Ad Set Schedule Invalid

The start date, end date, or dayparting schedule you configured for the ad set is invalid. Common causes include setting an end date in the past, setting a start date after the end date, or specifying dayparting hours that are impossible in the selected timezone.

What causes this error?

The start date, end date, or dayparting schedule you configured for the ad set is invalid. Common causes include setting an end date in the past, setting a start date after the end date, or specifying dayparting hours that are impossible in the selected timezone.

How to fix it

1. Check your dates: Ensure the start date is in the future (or ‘now’) and the end date is after the start date.
2. Verify timezone: Ad set schedules use the ad account’s timezone. If your API calls use UTC but your account is set to EST, the time conversion might push dates into the past.
3. Fix dayparting: If using daypart scheduling, ensure you’ve selected at least one active hour block for each active day—an empty schedule means no delivery windows.
