Quick answer: Go to your campaign's Ad Schedule tab, add time blocks for the days and hours you want, and layer bid adjustments to push harder during proven peaks.
What Is Ad Scheduling in Google Ads?
Ad scheduling controls exactly when your ads are eligible to appear. Without it, Google runs your campaign all day, every day.
Default behavior (all day)
Per Google's Ads Help Center, every new campaign defaults to "All day." That means your budget competes around the clock, whether or not customers are ready to act.
Why scheduling matters
Running ads at 3 AM wastes money if your audience sleeps. Scheduling keeps your budget focused on hours that produce results. You spend less. You convert more.
Compatibility note (not for App campaigns)
Google Ads documentation confirms that ad scheduling is not available for App campaigns. Every other campaign type supports it, including Search, Display, and Shopping.

When to Use Ad Scheduling
Use scheduling when your data shows clear performance peaks, or when your business can only respond to leads during specific hours.
Business hours scheduling
A B2B company with a 9-to-5 sales team should not pay for midnight clicks. Scheduling stops spend outside working hours entirely.
Peak performance times
Pull your Day and Hour report first. Find the hours with the best CTR and lowest CPC. Build your schedule around those windows.
Reaching customers by timezone
Ad schedules run on your account's time zone. If your customers sit in a different zone, adjust your schedule to match their peak hours, not yours.
Example: when audience converts most
Say your data shows 80% of conversions happen between 7 AM and 9 PM on weekdays. Schedule those windows and cut the rest. Let the data lead.

How to Set Up an Ad Schedule in Google Ads
This takes under five minutes. Follow each step.
Navigate to Ad Schedule
In Google Ads, open the Campaigns menu on the left. Select "Ad schedule." Click the pencil icon to start creating a schedule for a specific campaign.
Select days and times
Pick your campaign from the list. Choose the days and time ranges you want ads to run. You can create up to 6 ad schedules per day per campaign, per Google's setup documentation.
Create multi-day schedules correctly
Want to run ads from Monday 11 PM through Tuesday 7 AM? You must create two separate schedule blocks. One for Monday (11 PM to midnight). One for Tuesday (midnight to 7 AM). A single block cannot cross two calendar days.
Save and review
Save your schedule. Confirm the time blocks look correct in the Ad Schedule view. Double-check that the time zone shown matches your account setting.

Optimize with Bid Adjustments
Scheduling controls when ads run. Bid adjustments control how aggressively you compete during those windows.
Why adjust bids for scheduled times
During peak hours, more advertisers are active. Raising bids for those windows helps you win the auctions that matter most.
Increase bids during peak hours
In the Ad Schedule tab, each time block has a bid adjustment field. Per Google Ads documentation, you can increase bids by up to 900% or decrease by up to 90%.
How bid adjustments compound
Multiple adjustments multiply together, they do not add. A +10% time-of-day adjustment combined with a +20% location adjustment equals base bid x 1.10 x 1.20. Factor that in before setting large percentages.
Percentage ranges and examples
Start small. A +15% to +25% adjustment on your top two or three hours is a safe first move. Review after two weeks, then adjust again.

Monitor Performance by Day and Hour
Your schedule is only as good as your follow-up.
View Day and Hour report
In Google Ads, go to Reports. Select "Day and Hour" from the predefined report options. This breaks performance down by day of week and hour of day.
Metrics to track (clicks, CTR, CPC, cost)
Watch clicks, CTR, CPC, and total cost. High CTR with low CPC during a specific hour is a clear signal to add more budget there.
Refine schedule based on data
Cut time blocks where cost is high and conversions are zero. Shift that budget to windows with proven results. Review every two to four weeks.
Adapt to shifting audience behavior
Audience patterns shift with seasons and promotions. A schedule that worked in Q1 can underperform in Q4. Regular reviews keep your schedule current.

Ad Scheduling Best Practices
Six rules to keep your schedule dialed in.
Consider account timezone
Your schedule runs on the account's time zone set at creation. Per Google's policy notes, that setting is permanent in standard accounts. Know your account's time zone before building any schedule, and back-calculate from your target customers' local time.
Handling schedules across midnight
Never build a single block crossing midnight. Split it into two. End Monday at midnight. Start Tuesday at midnight.
Regular review and optimization
Set a recurring calendar reminder. Two-week reviews are the minimum. Stale schedules waste money.
No scheduling if search volume is unpredictable
If demand could spike at any hour, scheduling cuts you off. For always-on intent, keep "All day" or broaden your windows. Scheduling works best when your audience has predictable patterns, not erratic ones.

Frequently Asked Questions
How many ad schedules can I create per day in Google Ads?
You can create up to 6 ad schedules per day for each campaign in your account.
Does ad scheduling work with Google App campaigns?
No. Ad scheduling is not compatible with App campaigns. It works with Search, Display, Shopping, and most other campaign types.
What timezone does Google Ads use for ad scheduling?
Google Ads uses your account's timezone, which is set when the account is created. In standard accounts this setting is permanent, so always account for your customers' local time when building your schedule.

Not in a single block. You must create two separate schedules: one for Monday ending at midnight, and one for Tuesday starting at midnight.
