Daylight Saving Time (DST) starts on different dates depending on the region:
- In the United States and Canada, DST starts on the second Sunday in March at 2:00 a.m., when clocks are set forward one hour.
- In the European Union and many other parts of Europe, DST starts on the last Sunday in March at 1:00 a.m. UTC, when clocks are set forward one hour.
- In parts of Australia (e.g., New South Wales, Victoria), DST starts on the first Sunday in October at 2:00 a.m., when clocks are set forward one hour.
For 2025 specifically:
- In the US and Canada, DST started on March 9, 2025.
- In the EU, DST started on March 30, 2025.
- In parts of Australia, DST will start on October 5, 2025.
The general concept of DST is to move clocks forward in spring ("spring forward") to have more daylight in the evening, and move them back in fall ("fall back") to have more daylight in the morning.
