About Sudha Yoga

What is Sudha Yoga?

Sudha Yoga (शुद्ध योग) is an auspicious Panchang combination whose name derives from “Shuddha”, meaning “pure” or “cleansed”. Like Siddha Yoga, it belongs to the family of three-way Tithi-Nakshatra-Vaara (weekday) combinations, but it draws on a narrower, more selective set of qualifying Tithi-Nakshatra pairs, which is why it forms comparatively less often through the year.

Astronomical Formation

Sudha Yoga forms only when a specific Tithi and a specific Nakshatra coincide on a particular weekday, with each of the seven weekdays keyed to its own qualifying pair. On most weekdays the qualifying Tithis are the 5th (Panchami) or 7th (Saptami), paired with a small, weekday-specific set of Nakshatras — for instance, Ravivara (Sunday) requires Panchami or Saptami together with either Pushya or Mula Nakshatra, while Guruvara (Thursday) instead requires the 13th Tithi (Trayodashi) together with Punarvasu, Pushya, or Revati. Because it needs three independently cycling Panchang elements — Tithi, Nakshatra, and Vaara — to align on this narrower pairing, Sudha Yoga windows appear irregularly and comparatively rarely across the year, and each window is shown split at local sunrise in line with the Vaara boundary.

What Sudha Yoga is Good For

True to its “pure” meaning, Sudha Yoga is traditionally regarded as a favourable and cleansing window, suitable for:

  • Purificatory Rites: Shuddhikaran (purification) ceremonies, sacred baths, and other cleansing rituals.
  • Religious Observances: Puja, havan, vratas, and other worship activities.
  • New Undertakings: Beginning ventures or tasks where a clean, unblemished start is sought.
  • Auspicious Ceremonies: General auspicious functions, in line with its overall favourable classification.

Important Considerations

Because Sudha Yoga requires a rarer Tithi-Nakshatra pairing than Siddha Yoga, it occurs on fewer days across the year — always verify the exact date and time window for your city before planning around it. As with any Panchang yoga, confirm that no conflicting inauspicious combination or Rahu Kalam overlaps with the window, and check local sunrise timings since the display splits at sunrise.

Frequently Asked Questions about Sudha Yoga

Sudha Yoga is an auspicious Panchang combination formed when a specific Tithi and Nakshatra coincide on a particular weekday. Its name means 'pure', and it is considered a purifying, favourable window.
Both are Tithi-Nakshatra-Vaara combinations, but they use different, independently defined qualifying tables. Sudha Yoga draws on a narrower set of Tithi-Nakshatra pairs than Siddha Yoga, so it forms on fewer days across the year.
Yes, Sudha Yoga is traditionally considered favourable for purificatory rites, puja, havan, vratas, and other worship activities, as well as for beginning new undertakings.
No. Sudha Yoga requires a relatively rare Tithi-Nakshatra pairing on top of a matching weekday, so it forms less often than broader combinations such as Siddha Yoga.
Sudha Yoga windows are computed from the exact Tithi and Nakshatra transitions combined with the local sunrise-to-sunrise weekday for your selected city's coordinates and time zone.
Yes. Even though Sudha Yoga itself is auspicious, it's good practice to confirm no conflicting inauspicious yoga or Rahu Kalam overlaps with the exact window before finalising important plans.
