Notification Snooze

Depending on your settings, when a reminder is due, a notification can appear on your lock screen, in your Notification Center, or as a banner on the top of your screen, or as a popup alert.

New in iOS 8, you can directly mark a reminder complete from these notifications, or you can also choose to defer your reminder.

The setting in Due > Notification Snooze controls how long a reminder can be deferred for in the notification.

By default, the Notification Snooze is set to "1 hour".
