Daylight saving right now
New Zealand Standard Time
Pacific/Auckland is currently on NZDT (UTC+13:00), its daylight-saving clock. That is not NZST. This page is named for the abbreviation people search for, and tells you the truth about which one is actually in force.
next change: Sun, 4 Apr 2027 02:00 local → NZST (188 days, clocks go back)
NZST is UTC+12 and applies during the southern winter. From late September to early April New Zealand runs NZDT (UTC+13).
Greenwich Mean Time
Etc/GMT is on GMT (UTC+00:00).
no clock change scheduled: fixed at UTC+00:00
GMT is UTC+0 and never shifts. The UK observes GMT in winter only: in summer it is on BST (UTC+1), so "GMT" on a British invite dated in July usually means BST.
Best time to call green = 09:00 to 18:00 on both sides
No overlap inside a 09:00 to 18:00 day on both sides. Someone has to take an early or late slot, and the table below shows exactly which hours are least bad.
