Daylight saving right now
Central Daylight Time
America/Chicago is currently on CDT (UTC-05:00), its daylight-saving clock.
next change: Sun, 1 Nov 2026 01:00 local → CST (80 days, clocks go back)
CDT is US Central Time in summer, UTC-5 — the same offset as winter EST, which is a classic source of one-hour scheduling bugs.
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.
