[Setting] Advanced settings [Learn more] Using custom ad scheduling [Description] 
Once you’re comfortable using AdWords’ most essential settings, consider adopting one or more of these optional features to help get your ad campaign on the same schedule as your customers (these settings are available for campaigns with "All features" enabled): Schedule: Set a campaign start and end date. Ad scheduling: Choose certain days or hours of the week for your ads to show. Ad delivery: By default, AdWords shows your ads when they're more likely to get clicks or conversions, but you can choose to show your ads more evenly throughout the day.
