How do I apply a filter on date & time?

You can apply filters in your Dashboard, Reports, and Widgets for a specific date or time. Several useful options are available for this, such as quick preset selections or a custom range. 

Use the quick selections to quickly apply a commonly used preset selection, or use a custom range to view, for example, the last 72 hours. This is especially useful when setting up newsletters, allowing you to send news from Friday, Saturday, and Sunday (the last 72 hours) on Monday.

Via the Dashboard and a Report, use the Date filter to choose an option.

For a Widget, first edit the report, then click the filter icon on the widget and select Date to choose an option.
