EST or EDT? People search “EST”, “CST” or “PST” all year, but those names only apply in winter. From March to November US clocks are on daylight time (EDT, CDT, MDT, PDT), one hour later. This page uses the real local time in each US zone, so the answers are right whichever season you read it in. More in our EST vs EDT guide.
