Greenwich Mean Time
Etc/GMT is currently on GMT (UTC+00:00).
no clock change scheduled — this zone is 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.
Eastern Standard Time
America/New_York is on EDT (UTC-04:00).
next change: Sun, 1 Nov 2026 01:00 local → EST (80 days)
EST is the winter half of US Eastern Time. From the second Sunday in March to the first Sunday in November, New York is on EDT (UTC-4) instead — so half the year an "EST" meeting invite is off by an hour.
