Backpack Calendar released
37Signals has released Backpack Calendar, a Web-based calendar for its Backpack tool that manages to-do's, notes, and ideas. The calendar is designed to be familiar to Apple iCal users, supporting sharing of Backpack Calendars as well as subscription to other calendars via the iCalendar format. The Backpack Calendar works well with Safari, according to 37Signals, and incorporates drag-and-drop events for most features. The tool supports multiple calendars, multi-day events, and email/SMS reminders. Backpack is priced from $5-14 per month, requiring Safari, Firefox, or Internet Explorer 6.
