If you only want your Google Ads to run at specific times on specific days, then you should use an ad schedule. Setting an ad schedule is easy with Google Ads and you can do it for individual campaigns while you are creating them or even after you launch them. The Google Ads Ad Scheduling will use your account's time zone when you are setting your time. Therefore, you need to make sure the time zone matches the business you are advertising for. You can choose to use a 12-hour clock or a 24-hour clock. In addition, you can choose to set a schedule for Monday-Friday, you can set a schedule for individual days, you can set a schedule for Saturdays-Sundays, and you can choose to run at certain hours for the entire week
