When this period operated
Period 6 of the 玄空 (Xuan Kong) Flying Star cycle ran from 1964 to 1983. Buildings constructed during this 20-year window carry a permanent Period 6 anchor in their natal period chart.
The ruling star: 六白 (Six White)
Each of the nine periods is governed by a different star number from the Luo Shu (洛書) sequence. Period 6's ruling star is 六白 (Star 6 Six White), of the metal element, classically associated with the northwest palace and the 乾 trigram.
六運:六白武曲星當令。主官位、權威、富貴、家業興隆。
Classical Xuan Kong reading for Period 6.
Buildings constructed during Period 6
Period 6's ruling star (六白) is the 武曲星 (martial-prosperity star), classically associated with authority, leadership, military / government careers, and household wealth. Buildings anchored in Period 6 carry a register supportive of formal achievement, status, and intergenerational wealth-transmission. Singapore housing stock from 1964–1983 spans the second wave of HDB development, the rise of mass-market private condominiums, and many resale apartments still in active use.
Modern relevance: reading Period 6 buildings today
Mid-vintage HDB blocks (built 1970s) and second-generation private apartment stock anchor here. For occupants of these properties, the period-6 register is favourable for households focused on career authority, formal leadership roles, or wealth consolidation. The natal Period 6 anchor read against current Period 9 produces specific period-interaction patterns that an audit can read precisely.
The natal Period 6 anchor stays with the building permanently. To read a Period 6 home in the current Period 9 (2024–2043), the natal period chart is overlaid with the Period 9 transit pattern — that interaction determines which sectors of the home are activated each year. 2027 Annual Feng Shui and 2028 Annual Feng Shui cover the year-by-year overlay.
Why generic Period 6 guidance fails
The period anchor is one layer of the feng shui reading, not the whole reading. The household's actual experience also depends on the building's 阳宅三要 configuration (door, master bedroom, stove octants — see FS-8: Singapore HDB & Condo for the door×master matrix), the occupants' personal BaZi and Zi Wei Dou Shu charts, and the year-on-year flying-star transits. Generic per-period guidance can name the natal anchor and the most-watched register; it cannot tell you which patterns activate for your household. Master Sean Chan’s blog post on the chart-house interconnection covers this multi-layer reading.
