| Date | Change | Local clock | New offset |

| Sunday, 3 October 2027 | Forward 1 hour | 02:00 → 03:00 | UTC +10:30 |
When clocks go forward, sunrise and sunset both happen an hour later by the clock — darker mornings, lighter evenings — and the night of the change is an hour shorter. When they go back, the reverse applies.
