NDT time now (Newfoundland Daylight Time)

What NDT means

NDT stands for Newfoundland Daylight Time, UTC−2:30. It is used in Newfoundland and southeastern Labrador.

It is a summer time: the daylight saving form of NST (UTC−3:30), one hour ahead. In St Johns it applies from March to October/November: from the second Sunday of March at 2:00 AM to the first Sunday of November at 2:00 AM.

Where and when NDT is used

1 zone uses it for part of the year only, switching back to standard time in the other months. Computed from tzdata under the current rules.

How long NDT has been used

In the tzdata record, St. John's has used NDT since 1917.

NDT converted to other zones

Every column is a fixed offset, so this table is valid on any date. Remember that the regions behind some columns switch to summer time (EST to EDT, CET to CEST, GMT to BST); the clock in those cities is then an hour later than the column.
