Does Adelaide observe daylight saving time?+
Yes. In 2026 the clocks change on 4 April 2026 and 3 October 2026.
Why does one local time sometimes have two answers?+
When clocks go back, the hour before the change repeats, so that local reading happens twice and both instants are valid. When clocks go forward, the skipped hour never occurs, so that reading has no matching instant at all. The converter reports both cases rather than guessing.
