Central Standard Time (CST)
Central Standard Time (CST) spans a massive North and Central American corridor—from Canada’s Prairies to Nicaragua’s Pacific coast. About half the region observes daylight saving, so one of the trickiest parts of working here is remembering which clocks spring forward and which don’t.
+Mexico, Belize, and Central American nations generally keep UTC‑06:00 year‑round, while the U.S. and Canada switch between CST and CDT. That’s why only 12 of the 25 member zones observe DST.
República Dominicana is not a member of the CST region; it follows Atlantic Standard Time (UTC‑04:00) and does not observe daylight saving.
Mexican zones like BahĂa Banderas and Chihuahua, plus Belize, Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua—none of these places practice DST, keeping their clocks steady all year.
The United States and Canada are the main DST observers in this region, switching between CST and CDT during the summer months.
BahĂa Banderas discontinued daylight saving on 30 October 2022 at 01:00 CST (UTC‑06:00), aligning with Mexico’s nationwide policy change.
NIC briefly experimented with DST to save energy during the oil crisis, switching to UTC‑05:00 between 1973 and 1975, then again during the 1990s, before abandoning it for good.
Because northern Mexican CST zones keep UTC‑06:00 year‑round while cities like Chicago shift between UTC‑06:00 and UTC‑05:00, meeting times can flip hour-by-hour in spring and fall unless teams explicitly confirm time offsets.
Certain U.S. regions like parts of Indiana didn’t universally adopt DST until the mid-2000s, creating temporary one-hour mismatches with neighboring states for several years.
Right after the “fall back” transition, Mexico City (UTC‑06:00) briefly shares the same clock time as Chicago (UTC‑06:00) before the U.S. clock shift reduces the gap to zero, creating a short window of perfect alignment.
