# Configure Consent Expiration in the Cookie Banner

This section explains how to configure the **consent expiration** in your cookie banner so that it automatically reappears after a specific time to request consent again.

In this example, the expiration is set to **6 months**. After this period, the banner will show again to collect updated consent.

---

## Example Implementation

```javascript
<script>
  // === CONFIGURATION: set consent expiration time ===
  // 6 months = 1000 ms * 60 s * 60 m * 24 h * 30 days * 6 months
  var wait = 15552000000; // milliseconds for six months
  
  function reopenWidget() {
    if (!window.bigidcmp) return;
    
    var consent = window.bigidcmp.getConsent();
    if (consent.updatedAt < (Date.now() - wait)) {
      window.bigidcmp.deleteConsent();
      window.bigidcmp.showWidget();
    }
  }
  
  if (window.bigidcmp && window.bigidcmp.getConsent && window.bigidcmp.showWidget) {
    reopenWidget();
  } else {
    window.addEventListener('bigidcmp:widget_ready', reopenWidget);
  }
</script>
```

## How to Change the Expiration Period

You can easily customize how long consent remains valid by modifying the `wait` value. This variable defines the duration **in milliseconds** before the banner reappears.

| Duration | Formula Example | `wait` Value |
| --- | --- | --- |
| **1 week** (default example) | `1000 * 60 * 60 * 24 * 7` | `604800000` |
| **6 months** (current example) | `1000 * 60 * 60 * 24 * 30 * 6` | `15552000000` |
| **12 months (1 year)** | `1000 * 60 * 60 * 24 * 30 * 12` | `31104000000` |

## Result

Once the defined expiration period passes, the stored consent is considered **expired**. When users return to your website after that time, the **cookie banner will automatically reappear** to request their consent again.
