As a council-watcher, I live by the City Council & committee meeting schedule. You can download the schedule, but it’s not live—you need to check the web version or follow the City Clerk on Twitter to make sure a meeting hasn’t been cancelled or rescheduled.
To make things easier for myself (and hopefully others), I’ve imported the schedule into Google Calendar and am updating it manually as necessary. You can add it to your own calendar for timely notifications!
