Newfoundland Daylight Time (NDT)

Newfoundland Daylight Time (NDT) operates at UTC−2:30 as the daylight saving time observed in Newfoundland and the southeastern coast of Labrador. Sometimes simply referred to as "Newfoundland Summer Time," NDT is the daylight counterpart to Newfoundland Standard Time (NST, UTC−3:30) and is typically in effect from early March to early November.

Importance and Global Use of NDT

NDT helps residents and businesses in Newfoundland and southeastern Labrador make better use of extended daylight during the summer months, supporting tourism, outdoor activities, and evening commerce. This shift allows local services, transportation, and public safety to adapt to seasonal daylight patterns, which is particularly useful given Newfoundland's northern latitude.

Internationally, NDT maintains Newfoundland's unique half-hour time distinction while allowing easier coordination with Atlantic and North American partners. By aligning more closely with Atlantic Daylight Time in neighboring provinces, NDT supports smoother communication, trade, and travel scheduling across eastern Canada and international partners in North America.
