Dates when your ad campaign is running
Start and end dates determine the duration of a campaign. You can enter these dates in your campaign settings
By default your start day is the current day. If you do not change this date, then the system will start serving your ads as soon as they pass moderation and are paid for. If you change the start date of a campaign in progress to a later date, then ads will be stopped within 60 minutes and will resume at 00:00 Moscow Time on the new start date.
Set the end date for your campaign if you know exactly when it should end (for example, if you are running a promotion or sale). You can pause, resume or delete an ad campaign at any moment up through the end date .
You can't set the starting and ending time for your campaign. A campaign begins serving ads from 00:00 Moscow Time on the start date and stops serving ads at 23:59 Moscow Time on the end date regardless of your selected time zone. If you set time targeting for your campaign, then it will start and end at the times indicated in your settings for the corresponding days of the week.
