We recently added repeating events to the Backpack calendar. We've always supported repeating events that were brought in via an iCalendar subscription, but now you can create your own repeating events.
When you add an event you can repeat it every day, every week, every other week, every month, and every year. The event can repeat up to 50 times. You'll find the "Repeat" pulldown right below the "Calendar" pulldown in the sidebar when adding an event.
We hope you like this new feature.
