Time and day targeting is particularly useful for campaigns related to time-specific products, such as tickets to sporting events or ads for a television series that airs on a particular day. You can also use time and day targeting to reach particular demographics or groups of users engaged in time-related activities. For example, if your target audience is students, you might serve ads only during after-school hours. Or you might promote a quick-recipe site in the hours just before dinner.
