About Halaahal Yoga

What is Halaahal Yoga?

Halaahal Yoga (हलाहल योग) is one of the rarer Tithi-Nakshatra-Vaara (weekday) combination Yogas found in traditional Panchang. Its name comes from “Halaahal,” the deadly poison that emerged during the Samudra Manthan (churning of the cosmic ocean) and was consumed by Lord Shiva to protect creation. In keeping with that name, Halaahal Yoga is treated as an inauspicious window, best kept in mind when planning significant activities.

Astronomical Formation — The Exact Rule

Unlike simpler Vaara-Tithi Yogas, Halaahal Yoga requires three conditions to align simultaneously: a specific weekday (Vaara), a specific lunar day (Tithi), and the Moon transiting a specific Nakshatra — all on the same day. Because all three must coincide, this is a genuinely rare combination, occurring on only one qualifying Tithi-Nakshatra pairing per weekday:

  • Sunday (Ravivara): Panchami Tithi with Moon in Krittika Nakshatra
  • Monday (Somavara): Dwitiya Tithi with Moon in Chitra Nakshatra
  • Tuesday (Mangalavara): Purnima Tithi with Moon in Rohini Nakshatra
  • Wednesday (Budhavara): Saptami Tithi with Moon in Bharani Nakshatra
  • Thursday (Guruvara): Trayodashi Tithi with Moon in Anuradha Nakshatra
  • Friday (Shukravara): Shashthi Tithi with Moon in Shravana Nakshatra
  • Saturday (Shanivara): Ashtami Tithi with Moon in Revati Nakshatra

Because both the Tithi and the Nakshatra must match on the exact same weekday, Halaahal Yoga occurs only occasionally through the year — it is not a recurring weekly or fortnightly pattern like many other Vaara-Tithi yogas.

Why It Is Considered Inauspicious

Classical Muhurat texts list Halaahal Yoga among the combinations best avoided for beginning major, long-term undertakings — such as marriage ceremonies, Griha Pravesha (housewarming), laying a foundation stone, launching a new business, or signing significant contracts. It is not associated with personal harm; rather, it is treated as an unfavorable backdrop for starting things meant to last and flourish, similar in spirit to other cautionary Vaara-Tithi combinations such as Kulika or Yamaganda.

Important Considerations

Each Halaahal Yoga window is computed continuously and, matching Panchang convention, is displayed split at local sunrise. Since it depends on precise Tithi and Nakshatra boundaries that shift with your location's sunrise, always confirm the exact start and end times shown above for your city before making plans, and weigh it alongside any other yogas or muhurats active on the same day.

Frequently Asked Questions about Halaahal Yoga

Halaahal Yoga is a rare, inauspicious combination formed when a specific Tithi (lunar day), a specific weekday (Vaara), and a specific Moon Nakshatra all align on the same day. It is named after the poison 'Halaahal' from the churning of the ocean (Samudra Manthan).
The name comes from Halaahal, the deadly poison that emerged during Samudra Manthan and was consumed by Lord Shiva to save creation. The name signals that this Yoga is treated as a period requiring extra caution, not as a literal danger.
Most cautionary Vaara-Tithi yogas (like Kulika or Hutashan) need only a matching Tithi and weekday. Halaahal Yoga additionally requires the Moon to be in one specific Nakshatra, which makes it considerably rarer than those combinations.
Traditional Muhurat texts advise avoiding major long-term commitments — such as marriage, Griha Pravesha, foundation-laying, or signing important contracts — during Halaahal Yoga. Routine daily activities are not affected.
The timings depend on the precise astronomical positions of the Sun and Moon along with your city's local sunrise. Our calculator computes the exact continuous windows where the Tithi, Nakshatra, and weekday conditions are all satisfied for your chosen location.
Not necessarily on a fixed monthly schedule. Because it needs a Tithi, a Nakshatra, and a weekday to coincide exactly, Halaahal Yoga occurs only a handful of times through the year rather than on a regular weekly or fortnightly cycle.
