Durmuhurtham and Varjyam (Vishanadi) are classical inauspicious windows distinct from Rahu Kalam. Durmuhurtham refers to specific adverse Muhurthams among the 15 daylight Muhurthams, set by the weekday. Varjyam refers to a toxic 4-Ghatika (~96 minute) arc within each Nakshatra's transit. Both are traditionally avoided when starting brand-new enterprises, while routine ongoing daily work continues unaffected.
☕ Micro-Friction vs Macro-Timing
In traditional Indian calendar systems, not all inauspicious windows are calculated the same way. Most people are familiar with Rahu Kalam, which divides daylight into eight equal parts of about 90 minutes. However, the classical muhurtha tradition identifies two additional, more granular friction windows: Durmuhurtham and Varjyam.
Durmuhurtham is tied to the 30-part division of the day and night (15 muhurthams of daylight). Each weekday has one specific daytime Muhurtham of about 48 minutes, and Friday has two (e.g., Tuesday's 4th daytime Muhurtham; Friday's 4th and 9th). Varjyam (also called Vishanadi or Tyajyam), on the other hand, travels with the Moon: every single Nakshatra has a specific arc that tradition treats as unfavourable.
Neither window is a curse or reason for anxiety. They are simply tactical advisory pauses for high-stakes, irreversible beginnings, such as signing contracts, inaugurating homes, or conducting weddings.

Frequently Asked Questions
What is the difference between Durmuhurtham and Rahu Kalam?
Rahu Kalam is an 8-part daylight division lasting ~90 minutes, ruled by the shadow planet Rahu. Durmuhurtham is one of the 15 daylight Muhurthams (~48 minutes each), fixed as adverse for each weekday (e.g., Ravivara's 14th Muhurtham, Somavara's 9th Muhurtham). While South Indian traditions heavily track Rahu Kalam, Telugu and Kannada traditions track Durmuhurtham with equal prominence.
What is Varjyam (Vishanadi)?
Varjyam literally means 'that which should be abandoned'. Within the 60 Ghatikas (~24 hours) of any Nakshatra's transit, there is a specific 4-Ghatika span (~96 minutes) termed Vishanadi (poison duct). For example, in Rohini, the 40th to 44th Ghatika is Varjyam. Classical texts advise avoiding the inauguration of auspicious works during this arc.
What is Amrita Ghadia (Amrita Kalam)?
Amrita Kalam is the traditional counterpart of Varjyam: a 4-Ghatika window of nectar (Amrita) within each Nakshatra, considered highly auspicious for new beginnings. Its starting Ghatika comes from its own per-Nakshatra table in the classical texts; it is not a fixed offset from Varjyam. (Nava shows Varjyam but does not currently list Amrita Kalam.)
Do I need to worry if an ongoing task runs into Durmuhurtham?
No. Classical Jyotish texts explicitly clarify that adverse muhurthams apply only to the *moment of commencement* (Aarambha). Tasks already in motion continue without obstacle.

⏱️ Nakshatra Vishanadi Starting Ghatikas
Each Nakshatra has an exact starting Ghatika (out of 60) where its 4-Ghatika Varjyam begins:
Ardra: 21 | Punarvasu: 30 | Pushya: 20 | Ashlesha: 32 | Magha: 30
Varjyam Span = Start Ghatika to (Start Ghatika + 4 Ghatikas)
1 Ghatika = 24 Minutes | 4 Ghatikas = 96 Minutes (proportional to star duration)
