This one is a list of all upcoming news events (including when speeches by bank heads are being given). But the best bit of this one is that the times given depend on your own computer's settings, so it will always be the right time for your timezone. Also updated fairly quickly, eg, within a couple of minutes of the event - sometimes within seconds.
Has consensus forecasts for data, and ranks events according to importance, too, so you can often just ignore all but the red ones.
Thanks for the calendar above paulbooma, just what I've been looking for with the bill auction times...
