Read from the ten-day cycle your day pillar (or year pillar) belongs to: the two branches the cycle never reaches are void.
By the sixty stem-branch cycle: the Jia-Zi cycle is void at Xu and Hai; Jia-Xu at Shen and You; Jia-Shen at Wu and Wei; Jia-Wu at Chen and Si; Jia-Chen at Yin and Mao; Jia-Yin at Zi and Chou.

In practice it reads as expectations falling through and effort being discounted. The classics also say a void palace suits quiet work, nominal posts and study; in practical terms, do not put all your resources in one place.
Used: it appears in chart conclusions and advice as a note that strength is reducedIt also appears as an on-chart hint only, which does not enter any score.
Rule of thumb: these markers are read from fixed classical tables, and the scores and advice come from a separate model. Both are laid out on the site, and neither is a claim about what will happen.
These readings follow the traditional Chinese system (BaZi / Zi Wei Dou Shu) and describe how the classics read a chart. They are not predictions and not medical, legal or financial advice, and no outcome is promised.
Does void mean nothing works?
No. The traditional handling is reduced strength rather than cancellation: whichever pillar it falls in is the area where effort counts for less.
Can the void be filled?
The tradition holds that when a luck cycle or annual year reaches that branch, it is filled and the strength returns.
