What Time Zone Is [State]?
PST or PDT? CST or CDT? EST or EDT? MST or MDT? — Complete guide to every US state's time zone, current abbreviation, and DST status.
Quick Answer: What Time Zone Is My State?
The US has 4 main mainland time zones — Eastern, Central, Mountain, and Pacific — plus Alaska and Hawaii. Each zone uses two abbreviations: a standard time (winter) and a daylight time (summer). For example, California is always Pacific Time, but it's PST (UTC-8) in winter and PDT (UTC-7) in summer. Right now in April 2026, all DST-observing states are on their summer (daylight) abbreviation.

Direct answers to the most common location-based time zone queries.
Is California PST or PDT?
California is in the Pacific Time Zone. In winter (November–March), California uses PST (Pacific Standard Time, UTC-8). In summer (March–November), California uses PDT (Pacific Daylight Time, UTC-7). Right now in April 2026, California is on PDT (UTC-7).
California observes Daylight Saving Time. Clocks spring forward on the second Sunday of March and fall back on the first Sunday of November. The entire state — from San Diego to San Francisco to Los Angeles — uses the same Pacific Time zone.
Is Texas CST?
Yes — most of Texas is in the Central Time Zone. In winter, Texas uses CST (Central Standard Time, UTC-6). In summer, Texas uses CDT (Central Daylight Time, UTC-5). Right now in April 2026, most of Texas is on CDT (UTC-5). The exception is El Paso and far west Texas, which use Mountain Time.
Texas is the second-largest US state and spans two time zones. The vast majority — including Houston, Dallas, San Antonio, and Austin — is on Central Time. Only the El Paso area (far west Texas) uses Mountain Time (MST/MDT), which puts it on the same time as Denver.
Is Ohio EST or EDT?
Ohio is in the Eastern Time Zone. In winter (November–March), Ohio uses EST (Eastern Standard Time, UTC-5). In summer (March–November), Ohio uses EDT (Eastern Daylight Time, UTC-4). Right now in April 2026, Ohio is on EDT (UTC-4).
Ohio is entirely in the Eastern Time Zone — there are no split zones within the state. All major cities including Columbus, Cleveland, Cincinnati, and Toledo observe the same Eastern Time. Ohio observes Daylight Saving Time on the same schedule as New York and the rest of the East Coast.
Is Denver MST or MDT?
Denver (and all of Colorado) is in the Mountain Time Zone. In winter (November–March), Denver uses MST (Mountain Standard Time, UTC-7). In summer (March–November), Denver uses MDT (Mountain Daylight Time, UTC-6). Right now in April 2026, Denver is on MDT (UTC-6).
Colorado is entirely in the Mountain Time Zone. Denver is often used as the reference city for Mountain Time. Colorado observes Daylight Saving Time — unlike neighboring Arizona, which stays on MST year-round. This means in summer, Denver (MDT, UTC-6) is one hour ahead of Phoenix (MST, UTC-7).
