Taipei is 16 hours ahead of Los Angeles during Pacific Standard Time (or 15 hours during PDT). Taipei uses Taiwan Standard Time (TST, UTC+8) while Los Angeles uses Pacific Time (PT, UTC-8/-7). When it's 12:00 PM in Los Angeles, it's 4:00 AM the next day in Taipei.
Taiwan does not observe daylight saving time, but California does. This means the difference varies between 15 and 16 hours throughout the year.
Best calling time: 9:00 PM - 12:00 AM Taipei time. This corresponds to 5:00 AM - 8:00 AM in Los Angeles (during PST), catching early morning hours on the West Coast.
Taipei and Los Angeles have strong tech and trade connections. Many California tech companies rely on Taiwanese semiconductor manufacturing, especially TSMC chips. Los Angeles also has a significant Taiwanese-American community. The substantial time difference requires evening calls from Taipei to reach LA business hours.
