Time Difference Between Boston and Los Angeles

There is a 3-hour time difference.

• Boston = Eastern Time (ET): EST (UTC-5) / EDT (UTC-4)
• Los Angeles = Pacific Time (PT): PST (UTC-8) / PDT (UTC-7)

⏰ Year-Round

• Standard Time (Nov–Mar): Boston 3 hours ahead (e.g., 12 PM Boston = 9 AM LA)
• Daylight Time (Mar–Nov): Boston 3 hours ahead (e.g., 12 PM Boston = 9 AM LA)

The 3-hour gap is constant because both zones observe DST on the same schedule (since 2007).

⚠️ Common Confusion

The original answer incorrectly stated "no time difference." Boston and LA are in different time zones — Eastern vs. Pacific.
