New York vs. California Time Difference: Always 3 Hours

New York (Eastern Time) is always 3 hours ahead of California (Pacific Time)—year-round, without exception.

Time Zone Mechanics

• Standard Time (Nov–Mar): EST (UTC−5) vs. PST (UTC−8) → 3-hour gap
• Daylight Saving (Mar–Nov): EDT (UTC−4) vs. PDT (UTC−7) → 3-hour gap

Both zones shift simultaneously (second Sunday March / first Sunday November), preserving the offset.

Practical Examples

Scheduling Implications

• Meetings: 9 AM–2 PM PT / 12 PM–5 PM ET = comfortable overlap
• Deadlines: "End of day" = 11:59 PM ET = 8:59 PM PT (CA gets 3 extra hours)
• Markets: NYSE/NASDAQ 9:30 AM ET = 6:30 AM PT (West Coast traders start early)
• Live Events: 8 PM ET sports = 5 PM PT (family-friendly on West Coast)

No Exceptions

Arizona (mostly MST, no DST) and Hawaii (HST, no DST) break the pattern—but they're not California. The NY–CA 3-hour difference is absolute and permanent under current law.
