# TimePeriod
<a name="API_TimePeriod"></a>

Sets the start date and end date for retrieving a cost estimate. The start date is inclusive, but the end date is exclusive. For example, if `start` is `2017-01-01` and `end` is `2017-05-01`, then the cost and usage data is retrieved from `2017-01-01` up to and including `2017-04-30` but not including `2017-05-01`.
