How do I know if I'm in Daisakkai?

Enter your birth date in the calculator above. The result will show your Six-Star type, your current cycle phase, and whether that phase is one of the three Daisakkai years (Shadow, Halt, Decline).

Is Daisakkai the same as a kill year?

In English, 'kill year' is sometimes used loosely. In Hosoki's original system, Daisakkai is a three-year window. The single-year term daichu-satsu refers to specific risk days inside or near that window, not the window itself.

What should I avoid during Daisakkai?

Hosoki traditionally advised against marriage, starting a business, changing jobs, moving house, major medical procedures, and large financial commitments during the three Daisakkai years. Modern practitioners often soften this — read these as 'don't initiate' rather than 'don't act at all'.

Can two people in Daisakkai marry?

Hosoki was emphatic that they should not. The teaching: wait until at least one of the two has cleared the cycle, ideally both.

Is Daisakkai connected to the Netflix show Straight to Hell?

Yes. Straight to Hell (2026, originally 地獄占星師) dramatises the life of Kazuko Hosoki, the inventor of Six-Star Astrology and the popularizer of the Daisakkai concept. The show's hook 'You'll go to hell' was Hosoki's actual on-air catchphrase.

How often does Daisakkai come around?

Every 12 years. Each Six-Star type cycles through the same 12 phases, with Shadow, Halt, and Decline always appearing as a consecutive three-year block once per cycle.

Does my Daisakkai start on January 1 or my birthday?

In the practitioner tradition followed by senjutsu.jp and daisakkai.net, the Six-Star year boundary is the Gregorian year — January 1 to December 31. Some folk practitioners use the lunar new year. This calculator uses the Gregorian convention.

Can I do anything to soften Daisakkai?

Hosoki taught that the three years are unavoidable in their existence but manageable in impact. Common advice: don't initiate, do consolidate, don't sign, don't move, take care of health, support existing relationships.
