Auspicious Contract Signing & Deal Closing Dates (立券交易吉日)

Open Interactive Date Picker

Select high-trust dates for M&A agreements, real-estate closings, employment contracts, and joint ventures.

Classical Canon Citation:

《通书·立券交易》：“立券盟约，贵乎信义相孚，宜择建、定、成、五合、六合之日，最忌破日、劫煞与空亡之辰。”

Prioritizes Establish (建), Stable (定), and Success (成) days where Heavenly Stems and Earthly Branches reinforce mutual commitment.

12-Officer Rule (建除十二神) & BaZi Alignment

Structural Selection Protocol for 立券交易吉日

Prioritize Stable (定日 · Locked Terms), Success (成日 · Mutual Profit), and Establish (建日); strictly avoid Break (破日) or Divide (除日) to prevent post-closing disputes.

Select a day whose Earthly Branch bridges the two signatories’ Year or Day Branches via Six Harmony (六合) or Three Harmony (三合), avoiding Xun Kong (空亡) void days.
