Calendar Wrong Daylight Saving

High Sierra, new iMac: "Calendar" pop-up says "Daylight Saving Time starts Tomorrow" (11 March).

It doesn't! I'm in Australia: Australian states that have DLS start on 1 April.
My "Calendar" correctly show timezone as ACST, and correctly shows DLS starting on 1 April, but also shows it starting tomorrow.
The reason, seen by clicking is that it is a part of the "Holidays in the United States" calendar. My preferences however aren't set to show this Calendar! Why is this so?

Even if I wanted to have the USA holidays show, I wouldn't want the DLS to show, as it would potentially mislead me and many others. Why is that association so?
Thanks, Paul.

iMac, macOS High Sierra (10.13.3)

Paul,


I can't answer your question specifically. However, I asked Siri when DST starts for me in the US and she said April 1. Luckily I found out it start for us here tomorrow (March 11). The cause of Siri's error? I had her voice set to "Australian English". When I set it to "US English", she reported correctly.
