Based on authentic feng shui principles there are “no formulas” to choose a date for “initial door-opening” or “key-collection ceremony” because there is no such “event“.
Legit feng shui principles fulfill 3 fundamentals. The trinity of 天 heaven , 地 environment 人human. I Ching call it 三才. Heaven refers to timing, human-us and environment essentially feng shui.
风水太极点 feng shui locus
Without the human factor to move into the house. In feng shui we call it “no feng shui tai ji locus point风水太极点” created. Thus no influences on house feng shui.
However a more relevant ritual/custom known as 旺五方 or 拜四角 (not feng shui) can be use to dispel negative energies. This custom applies to new or resale flats. You can choose an auspicious date to do it any time before renovation or move in. This got nothing to do with key collection nor open door ceremony.
Point 1. A myth not found in classic feng shui teachings
We are into a knowledge-based economy where concepts are proven by science or other means not hearsay. The process should be logical and objectives are clear. Key collection or door opening, from what i heard involves rolling of pineapple, sea salt, tea leaves etc supposedly to usher in good luck for your new home. If this occasion is so significant one should be able to find in feng shui classics on auspicious date selection. To me it draws similarity to wearing red on CNY or deposit money on Li Chun day. There are no reliable evidence from feng shui books backing these claims.
Point 2. No such event found in Chinese almanac calendar
To start with there is “no such event” as door opening listed in good old fashion Chinese almanac通胜. Where people used it for selection of auspicious dates & time thousand of years ago. You can thumb through till your fingers drop but there no such event as 开门, under the suitability 宜 column see illustration.
However there are events such for “shifting into” your new house call 入宅 and resale house call 移徙. One must also take into consideration of your Home Destiny for such important events. Other events related to new house feng shui includes renovation修造 and groundbreaking for new buildings 动土 because it involves the calculation of feng shui sectors 九宫八卦.
Point 3. No Significance unless you consume it
Choosing an auspicious date, technically the significance is when you “officially use or consume it” which is when you move in.
If common sense prevail, we have not stayed in the house and therefore no feng shui influence. Imagine if you owned 10 houses, only the house that you reside influence your luck. Not sure how this initial door opening was spun uniquely happening only in Singapore.
Point 4. Where is the relevance and objective
Next we examine the relevance for such action. If you wanted peace of mind why not choose an auspicious date to “complete the sale” where you are officially the legal owner of the house. This is definitely appropriate and reasonable.
Point 5. Why we choose auspicious dates ?
Back to the basic question why do we need to choose an auspicious date, in the first place?
This is either to speed up certain enhancement to bring good fortune or to avoid doing something wrong that may have bad repercussions. For instance we need to renovate the house and choosing a good date avoid the dangers of annual bad sectors like “3 killings 三煞方, or misfortune 5 五黄. Just like wedding dates to avoid conflict with couples’ birth profile.
Correct use of date selection produce rapid results and accurate outcome
Date selection for specific objectives does bring meaningful outcomes particular using feng shui formulas from qi men dun jia 奇门遁甲 or xuan kong da gua 玄空大卦 or bazi principles.
