PST vs EST — What You Need to Know

Pacific Standard Time (PST) is UTC-8. It covers the US West Coast, including California, Washington, Oregon, and Nevada. During Daylight Saving Time (March–November), it becomes PDT (UTC-7).

Eastern Standard Time (EST) is UTC-5. It covers the US East Coast, including New York, Florida, Massachusetts, and Georgia. During Daylight Saving Time, it becomes EDT (UTC-4).

The difference is always 3 hours — when it's 9 AM in Los Angeles, it's noon in New York. Because both zones observe DST on the same dates, the gap never changes to 2 or 4 hours.
