Use a set of Cron type Quartz triggers.

EG: Make a daily one that selects all the reminders for a given day (create a view with them). Then use a hourly one to process the reminders for that day - this will help you distribute the workload in 24hours. You can go further on up to your desired granularity for events (quarters, minutes).
