Day-Parting
Choose specific days and hours for your campaign to run so you only pay for impressions when your audience is most receptive.

What Is Day-Parting
Day-parting lets you schedule a campaign to run only during specific hours on specific days. Outside of those windows, the campaign pauses automatically and resumes when the next window opens.
TIP
A late-night pizza delivery service is the classic day-parting use case. Running ads only between 8 PM and 2 AM means you are paying for impressions exactly when people are placing orders — not at 9 AM when no one wants pizza.
How to Set Day-Parting

- 1In the campaign editor, go to Campaign Information.
- 2Toggle Day-Parting on.
- 3A day/hour grid appears. Select the days and hours you want the campaign to run.
- 4Save your selection and continue.
Common Mistakes
- 1Setting a window so narrow that the campaign delivers too few impressions — a 2-hour window on weekdays only leaves very little time for auctions to run. If delivery is much lower than expected, check whether day-parting is the constraint before adjusting budget or targeting. The campaign's Status will show Running during non-selected hours only if day-parting is the sole restriction, but impressions will be zero outside the window.
- 2Forgetting day-parting is still active after campaign setup — if you enabled day-parting during campaign creation and later wonder why your Running campaign shows $0 spend at certain hours, check the day-parting grid in Campaign Information. It will show exactly which hours are active.
- 3Not confirming which timezone governs the schedule — contact Topple support to confirm which timezone your day-parting windows are applied in before setting time-sensitive schedules.
