For iOS 8, make sure that the following is enabled:
Settings -> Notifications -> IconBadge -> Badge App Icon
This App allows the user to place useful information on the icon's notification area.
. Week number
. Day of Year
. Day of month
. Month and day
The information above is automatically updated at midnight even if the app isn't running.
NOTE: The icon badge is updated only if the iPhone has it's power on.
. User defined number.

constantly is being displayed in the App's icon.
This can be useful when an important
number must be remembered and quickly
. The icon information number can be removed.
