The current difference is shown at the top of this page. AST uses Atlantic Standard Time (AST, UTC−4) as standard time and Atlantic Daylight Time (ADT, UTC−3) during daylight saving time; NZST uses New Zealand Standard Time (NZST, UTC+12) as standard time and New Zealand Daylight Time (NZDT, UTC+13) during daylight saving time. The difference can change if only one side observes daylight saving time or if their clocks change on different dates. Choose your meeting date in the converter to check the applicable offset.
