Taiwan Bazi: Guide to Daylight Saving Time and True Solar Time
Were you born in Taiwan between 1945 and 1979? Understand the decisive impact of DST adjustments and longitude deviation on your Bazi time pillar.
Hidden Traps in Taiwan Bazi Charts
Many people born in Taiwan have completely incorrect Ba Zi (Four Pillars of Destiny) charts. Traditional charting tools directly read the clock time on your birth certificate, but the true Ba Zi calculation is based on the actual astronomical position of the sun (True Solar Time).
In Taiwan, this issue is amplified by two core factors: Daylight Saving Time (Summer Time) and Longitude Deviation. If you were born during the months when daylight saving time was in effect, your clock was artificially advanced by 1 hour. Without deducting this 1 hour, your Hour Pillar (which governs wealth, investments, and children in later life) will be severely skewed.
Taiwan Historical Daylight Saving Time Schedule (1945-1979)
During the summers from 1945 to 1979, the Taiwan government implemented 'Daylight Saving Time' multiple times to save energy. In these months, standard time was advanced from UTC+8 to UTC+9. If you were born during these summer months, you must deduct a full 1 hour before charting.
How Longitude Deviation Affects Your Chart
Taiwan's standard time is based on the 120° east longitude line (Beijing time / Central Standard Time). However, the actual longitudes of Taiwan's cities are slightly eastward:
Taipei City and New Taipei City
Located near 121.5° east longitude. The actual solar time is about 6 minutes ahead of clock time.
Taichung and Central Taiwan
Located near 120.6° east longitude. The actual solar time is about 2 minutes ahead of clock time.
Kaohsiung and Southern Taiwan
Located near 120.3°E. The actual solar time is almost exactly the same as the standard clock time.
Meta Universe Technology Solutions
You don't need to perform complex historical and geographical calculations yourself. The Meta Universe True Solar Time Calculator is specifically designed for this.
When you select your birth city and enter the date in the system, our cloud database automatically checks whether daylight saving time was in effect in Taiwan's history on that date, and adjusts for longitude to present you with a 100% accurate astronomical Ba Zi chart.
