As an "aristocrat" you now have the possibility to synchronize your dividend appointments with any calendar.
The synchronization will be updated regularly, so you will always see the current dividend dates in your calendar software.
For Google Calendar you can store the DivvyDiary calendar URL from the settings directly here.
For Apple Calendar you can find the instructions for subscribing to your DivvyDiary calendar here.
If you use another calendar software, look for an option to subscribe to iCal calendars.
