# Understanding campaign duration Campaign duration relates to the **number of days a campaign has been running since the first time it was launched.** These are the 3 rules used to calculate duration: * Paused timeframes are **excluded, and** play timeframes are **included** in the calculation; * the QA mode is not a status in itself, meaning that when the campaign is *Live in QA,* the timeframe is included in the calculation; * resetting data in the reporting erases the whole duration and resets the count to 0. Campaign duration can be accessed from the two following sections of AB Tasty: * **The test and personalization dashboard**, in the duration column ![Campaign\_duration.png](https://support.abtasty.com/hc/article_attachments/360022478400/Campaign_duration.png). * **The reporting of a campaign**, inside the activity card. Duration calculation is available only on campaigns launched after October 2020. If you wonder how long your test should run to be reliable, check out our [A/B Test Calculator.](https://www.abtasty.com/sample-size-calculator/) ## Functioning From the test and personalization dashboards, the duration column displays the number of days a campaign has been running.\ When hovering on the duration, a tooltip shows the following information: * The **creation date**: date and hour the campaign was created. * The **last played date**: date and hour the campaign was played for the last time. * The **last paused date** : date and hour the campaign was paused for the last time. The campaign duration is also displayed in the activity card of the reporting of each campaign. You can reset the campaign data you have collected so far by clicking the three dots on the top bar> *Clear data*.\ Once the data is cleared, the duration is reset to zero and calculation starts again from the date you cleared the data (if the campaign is live or in QA) or from the next time you play your campaign (if it is paused). Data is also collected from the time you enable a QA parameter in your campaign. We recommend clearing the data after finishing the QA of your campaign in order to start your campaign fresh, with data from your targeted visitors only. ## Use cases ### Use case 1: the campaign is currently live but has been paused several times. Let’s say it is the 16th of February 2021. Here is an example of campaign history: | **Action** | **Date** | **Status** | **Duration** | | ----------------------------- | ---------- | ---------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Create campaign | 02/02/2021 | Paused |
