What Time Zone Is Guatemala In?
Guatemala uses a single timezone: the primary designation is America/Chicago, which is currently UTC-06:00 from Coordinated Universal Time. The IANA Time Zone Database , the authoritative global reference used by operating systems, web services, and programming languages worldwide, lists this as America/Chicago.
Regional Context
Central America primarily operates on CST (Central Standard Time, UTC-06:00, the same as US Central Standard Time) with limited DST observance. Guatemala, Honduras, El Salvador, Nicaragua, and Costa Rica permanently observe UTC-06:00 without DST. Mexico's timezone situation is complex: most of Mexico observes CST/CDT (UTC-06:00/UTC-05:00) but Sonora (bordering Arizona) permanently observes MST (UTC-07:00, no DST). Belize observes UTC-06:00 permanently. Panama operates on EST (UTC-05:00) year-round, positioning itself in the Eastern timezone for business alignment with the United States. Scheduling between Central America and the US Eastern seaboard requires accounting for the 0-2 hour gap depending on country and season.
