Convert PST to EST: Pacific to Eastern Time Conversion
Converting from Pacific Time to Eastern Time is the reverse of the more common EST-to-PST conversion, but equally important. Whether you're in Los Angeles scheduling a call with New York, or a West Coast business coordinating with East Coast clients, adding 3 hours to Pacific Time gives you Eastern Time.
Time Zone Overview
Pacific Standard Time (PST)
Pacific Standard Time is UTC-8. It covers the western US including Los Angeles, San Francisco, Seattle, San Diego, and Las Vegas. During DST it becomes PDT (UTC-7).
Eastern Standard Time (EST)
Eastern Standard Time is UTC-5. It covers the eastern US including New York, Washington DC, Boston, Atlanta, and Miami. During DST it becomes EDT (UTC-4).
Conversion Formula
Time in EST = Time in PST + 3 hours
Conversion Examples
Example 1: 9:00 AM PST → 12:00 PM EST
Example 2: 7:00 PM PST → 10:00 PM EST
Daylight Saving Time Considerations
Both zones observe DST on the same schedule, so the 3-hour difference remains constant.
- PST/PDT: UTC-8 (winter) / UTC-7 (summer)
- EST/EDT: UTC-5 (winter) / UTC-4 (summer)
