What yoga is operative in San Francisco on 21 December 2025?

The yoga operative in San Francisco on 21 December 2025 is Dhruva, active from 3:05 AM to 3:10 AM local time. In the Vedic panchang, yoga is calculated from the combined longitudes of the Sun and Moon and cycles through 27 named yogas. Dhruva yoga carries its own quality and influences the day's overall character — affecting the auspiciousness of activities begun during its span.

ब्रह्म मुहूर्त

Panchang — the five angas पञ्चाङ्ग

Tithi, Nakshatra, Yoga, Karana and Vara with their end-times, plus the month and the Moon’s and Sun’s signs — computed for this city’s sunrise. Times after midnight use the traditional extended clock (e.g. 27:23 = 03:23 next morning).

Tithi: Dwitiyaद्वितीयाtill 21:22then Tritiyaतृतीयाtill 46:43
What this means
The lunar day. It is set by how far the Moon has pulled ahead of the Sun — each 12 degrees of separation is one tithi. The tithi shapes which activities the tradition favours, and it ends at the time shown, when the next one begins.

How we compute this panchang

Every time on this page is calculated from the actual positions of the Sun and Moon using the Swiss Ephemeris (the same high-precision astronomical engine used by professional astronomers), not from a printed almanac or a fixed table.

Sidereal zodiac, Lahiri ayanamsha — the standard used by the Indian government calendar (ayanamsha for this date: 24.2199°). All nakshatra, rashi, tithi and yoga boundaries follow from it.
Local true sunrise — muhurta windows (Rahu Kaal, Choghadiya, Hora, Abhijit and the rest) are measured from the true sunrise computed for San Francisco's exact coordinates, so they are correct for your location, not a regional approximation.
Two month conventions — we show both the Amanta (new-moon-to-new-moon) and Purnimanta (full-moon-to-full-moon) lunar month, because different regions of India follow different ones; an Adhika (intercalary) month is marked when it occurs.

Significance and auspicious/inauspicious flags are drawn from classical texts (Muhurta Chintamani, Brihat Samhita, the Puranas and others) and cited inline — we never assert an effect a text does not state.

Brahma Muhurta - San Francisco, 21 December 2025

On Sunday, the 21st of December 2025, the Vedic calendar in San Francisco carries a day of particular rhythmic quality. Sunrise arrives at 7:22 AM and dipping below the horizon at 4:53 PM, bringing 9 hours 30 minutes of daylight. The tithi is Dwitiya of the Shukla fortnight, and the nakshatra of the day is Purva Ashadha. The day carries the Dhruva yoga, completing the core panchang signature for 2025-12-21. Brahma Muhurta, the pre-dawn meditation window, runs from 5:46 AM to 6:34 AM.

In San Francisco, Rahu Kala runs from 3:41 PM to 4:53 PM — the period to avoid for new endeavours. The inauspicious direction (Disha Shool) for Sunday is West; new ventures toward the West are traditionally deferred. On the auspicious side, Labh choghadiya, running 9:45 AM to 10:56 AM, stands out as the best muhurta. Purva Ashadha nakshatra is under the lordship of Venus, bringing the ancient panchang frame into direct contact with San Francisco's horizon.
