n. — Science, especially Newfoundland
Daylight time in Newfoundland and parts of Labrador.
Type: 1. Origin — Newfoundland Daylight Time is observed (in 2016) from the second Sunday in March to the first Sunday in November. During the rest of the year, Newfoundland Standard Time is in effect. By statute, Newfoundland Standard time is to be 3.5 hours behind Greenwich Mean Time, or as it is also known, Coordinated Universal Time (UTC), and Newfoundland Daylight Time is to be 2.5 hours behind UTC (see Assembly of Newfoundland and Labrador reference). Newfoundland Time is not observed in any other province or country, making the term near-exclusive to Canada (see Chart 1), and especially to Newfoundland (see Chart 2). Daylight time was first instituted in World War 1.

- Newfoundland is the only place in Canada that chose not to adopt the standard one hour per meridian deviation from UTC, and instead adopted its own time zone with the deviation of 3.5 hours per three meridian, subtracting an extra half hour from UTC. Therefore, when it is 5 p.m. in Ontario, and 6 p.m. in the other Maritime provinces, it is 6:30 p.m. in Newfoundland (and some areas of Labrador).
- Older spellings generally do not capitalize daylight time; newer ones do.
