+# Schedule an app notification
+
+You can schedule an app notification to appear at a later time, regardless of whether your app is running at that time. This is useful for scenarios like displaying reminders or other follow-up tasks for the user, where the time and content of the notification is known ahead-of-time.
+
+Scheduled app notifications have a delivery window of 5 minutes. If the computer is turned off during the scheduled delivery time, and remains off for longer than 5 minutes, the notification will be "dropped" as no longer relevant to the user. If you need guaranteed delivery of notifications regardless of how long the computer was off, we recommend using a background task with a time trigger. For more information, see [Background tasks](/windows/apps/windows-app-sdk/applifecycle/background-tasks).
+
+For more information about app notifications, see [App notifications overview](index.md).
+
+
+## Schedule the notification
+
+To schedule a notification for a future time, use [**AppNotificationBuilder**](/windows/windows-app-sdk/api/winrt/microsoft.windows.appnotifications.builder.appnotificationbuilder) to define the notification content and the [**ScheduledToastNotification**](/uwp/api/Windows.UI.Notifications.ScheduledToastNotification) API to schedule it. The following example schedules a notification to appear 10 seconds from now.
+
+```csharp
+using Microsoft.Windows.AppNotifications.Builder;
+using Windows.UI.Notifications;
+using Windows.Data.Xml.Dom;
+
+var payload = new AppNotificationBuilder()
+    .AddArgument("action", "viewItemsDueToday")
+    .AddText("ASTR 170B1")
+    .AddText("You have 3 items due today!")
+    .BuildNotification()
+    .Payload;
+
+var doc = new XmlDocument();
+doc.LoadXml(payload);
+
+var scheduledNotification = new ScheduledToastNotification(doc, DateTimeOffset.Now.AddSeconds(10));
+scheduledNotification.Tag = "18365";
+scheduledNotification.Group = "ASTR 170B1";
+
+ToastNotificationManager.CreateToastNotifier().AddToSchedule(scheduledNotification);
+```
+
+The **Tag** and **Group** properties act as a composite primary key for the notification. Setting these values enables you to cancel or replace the scheduled notification later, as shown in the next section.
+
+
+## Cancel scheduled notifications
+
+To cancel a scheduled notification, retrieve the list of scheduled notifications from the [**ToastNotificationManager**](/uwp/api/Windows.UI.Notifications.ToastNotificationManager) and remove the one matching the tag you specified earlier.
+
+```csharp
+var notifier = ToastNotificationManager.CreateToastNotifier();
+var scheduled = notifier.GetScheduledToastNotifications();
+
+foreach (var notification in scheduled)
+{
+    if (notification.Tag == "18365")
+    {
+        notifier.RemoveFromSchedule(notification);
+    }
+}
+```
