tvcal turns the shows you follow into a calendar feed. Subscribe to it in Google Calendar once, and every upcoming episode appears with its air date, including new episodes announced later.

Yes. A calendar added “From URL” is a subscription. Google re-checks it periodically, so new episodes and rescheduled air dates appear without you doing anything.
