By default, an ad set can use all days and hours within its start and end dates. Use the day/time matrix only when delivery must be restricted.

Choose active periods

  1. Expand Day and Time range below the locations section.
  2. Use a day checkbox to select or clear all 24 hours for that day.
  3. Use individual cells for specific one-hour periods.
  4. Review the selected-hours total.
  5. Collapse the section after confirming the schedule.

Weekly day and hour delivery matrix

Each column represents Monday through Sunday. Each row represents one hour, such as 09:00–10:00.

Editing an existing schedule

Open campaign Edit, expand the matrix for the correct ad set, make the change, then save. The updated schedule can require another operational review.
