The Comprehensive Guide to Nepali Panchang: Astronomy, Tithis & Cultural Heritage
Timekeeping in Nepal and the broader Himalayan region is rooted in thousands of years of astronomical observation, Vedic geometry, and cultural devotion. While standard civil life across the globe operates on the Gregorian solar calendar, spiritual rituals, agricultural cycles, community festivals, and auspicious life milestones in Nepal strictly follow the Bikram Sambat (BS) calendar and the Vedic Panchang.
Generic online calendars frequently reduce the Panchang to simple Gregorian date converters or borrow approximate Indian ephemerides without accounting for Nepal's specific geographic coordinates and high-altitude horizons. Sripatro was created to restore absolute astronomical precision to Nepali timekeeping.
In this authoritative guide, we unpack the five core pillars of the Panchang, explain how solar and lunar celestial mechanics interact, demonstrate how to calculate auspicious timings (Muhurats), and explore the rich cultural traditions that make the Nepali calendar a living monument of Vedic science.
1. What is the Panchang? The Five Limbs of Time
The word Panchang (पञ्चाङ्ग) is derived from two Sanskrit roots: Pancha (meaning "Five") and Anga (meaning "Limb" or "Attribute"). In Vedic astronomy (Jyotish Vedanga), time is multidimensional. While a Gregorian day is simply measured as 24 linear hours from midnight to midnight, a Vedic day reflects the dynamic angular relationship between the Sun (Surya), the Moon (Chandra), and the 27 stellar constellations (Nakshatras).
The five limbs of the Panchang represent five fundamental cosmic coordinates:

Let us examine each limb in detail:
1.1 Tithi (The Lunar Day)
A Tithi is the duration in which the longitudinal angular distance between the Moon and the Sun increases by exactly 12 degrees. Because the Moon's orbit around the Earth is elliptical rather than circular, its speed varies from roughly 11.8° to 15.2° per day. Consequently, a Tithi does not last a fixed 24 hours—it can vary in length from roughly 19 hours to 26 hours.
There are 30 Tithis in a standard lunar month (Masa), divided into two fortnights (Pakshas):
- Shukla Paksha (Bright Fortnight): The waxing phase from the New Moon (Amavasya) to the Full Moon (Purnima), consisting of 15 Tithis (Pratipada, Dwitiya, Tritiya, Chaturthi, Panchami, Shashti, Saptami, Ashtami, Navami, Dashami, Ekadashi, Dwadashi, Trayodashi, Chaturdashi, Purnima).
- Krishna Paksha (Dark Fortnight): The waning phase from the Full Moon to the New Moon, consisting of 15 Tithis ending in Amavasya.
Tithi Classification and Spiritual Rulership
| Tithi Group | Sanskrit Name | Tithis Included (Shukla / Krishna) | Ruling Planet / Deity | Auspicious Activities |
|---|---|---|---|---|
| Nanda (Joyous) | नन्दा | 1st, 6th, 11th (Ekadashi) | Venus / Agni | Celebrations, spiritual initiations, Vratas, creative arts |
| Bhadra (Prosperous) | भद्रा | 2nd, 7th, 12th (Dwadashi) | Mercury / Lord Shiva | Travel, commerce, agriculture, buying vehicles |
| Jaya (Victorious) | जया | 3rd, 8th, 13th (Trayodashi) | Mars / Lord Ganesha | Legal matters, overcoming obstacles, physical training |
| Rikta (Empty/Void) | रिक्ता | 4th, 9th, 14th (Chaturdashi) | Saturn / Goddess Kali | Meditation, cleansing, debt eradication, spiritual shielding |
| Poorna (Full/Complete) | पूर्णा | 5th, 10th, 15th (Purnima/Amavasya) | Jupiter / Lord Vishnu | Weddings, Gruha Pravesh, big investments, consecrations |
1.2 Nakshatra (The Lunar Mansions)
In Vedic astronomy, the 360-degree zodiac belt is divided into 27 Nakshatras (lunar constellations), each spanning exactly 13 degrees and 20 minutes (13°20') of celestial arc ($360^\circ / 27 = 13^\circ 20'$). Each Nakshatra is further subdivided into 4 Padas (quarters) of 3 degrees and 20 minutes (3°20') each, corresponding to the 108 Pada divisions that govern the sound vibrations (Naam Akshar) assigned to newborn children.
The Moon traverses approximately one Nakshatra every 24.3 hours. The active Nakshatra at the precise moment of sunrise or birth determines an individual's emotional psyche, subconscious strengths, and the starting point of their Vimshottari Dasha planetary cycles.
Key Nakshatras and Their Astrological Significance
- Ashwini (0°00' - 13°20' Aries): Ruled by Ketu; deity: Ashwini Kumaras (physicians of the gods). Represents speed, healing, energy, and fresh beginnings.
- Rohini (10°00' - 23°20' Taurus): Ruled by the Moon; deity: Prajapati (Brahma). Highly fertile, creative, luxurious, and ideal for artistic and agricultural endeavors.
- Pushya (3°20' - 16°40' Cancer): Ruled by Saturn; deity: Brihaspati (Guru). Revered as the King of all Nakshatras (Nakshatra Raja), exceptionally auspicious for spiritual rites, starting new businesses, and purchasing gold or property.
- Magha (0°00' - 13°20' Leo): Ruled by Ketu; deity: Pitris (Ancestors). Represents lineage, authority, royal dignity, and ancestral honoring (Shradh).
- Swati (6°40' - 20°00' Libra): Ruled by Rahu; deity: Vayu (Wind). Symbol of independent movement, flexibility, commerce, and international ventures.
- Shravana (10°00' - 23°20' Capricorn): Ruled by the Moon; deity: Lord Vishnu. The star of divine listening, Vedic scholarship, education, and philosophical wisdom.
- Revati (16°40' - 30°00' Pisces): Ruled by Mercury; deity: Pushan (Protector of journeys). The final constellation signifying spiritual liberation, safe travels, and prosperity.
1.3 Yoga (The Solar-Lunar Angular Sum)
A Yoga is calculated by adding the celestial longitude of the Sun to the celestial longitude of the Moon and dividing the sum by $13^\circ 20'$ ($800'$):
$$\text{Yoga Index} = \left\lfloor \frac{\lambda{\text{Sun}} + \lambda{\text{Moon}}}{13^\circ 20'} \right\rfloor + 1$$
There are 27 Yogas in total. They act as subtle energetic filters affecting physical vitality, emotional harmony, and the collective atmosphere of the day:
- Auspicious Yogas (Shubha Yogas): Priti, Ayushman, Saubhagya, Shobhana, Sukarma, Dhriti, Vriddhi, Dhruva, Harshana, Siddhi, Variyan, Shiva, Siddha, Sadhya, Shubha, Shukla, Brahma, Indra. These Yogas enhance good fortune, smooth negotiations, and joyful outcomes.
- Challenging Yogas (Ashubha Yogas): Vishkambha, Atiganda, Sukarma, Dhriti, Shoola, Ganda, Vyaghata, Vajra, Vyatipata, Parigha, Vaidhriti. Ancient texts advise against initiating major worldly projects during periods governed by Vyatipata or Vaidhriti, recommending instead devotional prayer, introspective meditation, and charity (Daan).
1.4 Karana (Half of a Tithi)
A Karana is equal to half of a lunar Tithi, spanning an angular separation of 6 degrees between the Sun and the Moon. Since each lunar month consists of 30 Tithis, there are 60 Karanas in every lunar cycle.
The 60 Karanas are generated by a rotating cycle of 7 Movable (Chara) Karanas and 4 Fixed (Sthira) Karanas:
The 7 Movable Karanas (repeating 8 times throughout the month):
- Bava (बव): Auspicious for health, fitness, and starting beneficial enterprises.
- Balava (बालव): Favorable for educational pursuits, intellectual inquiry, and Vedic rituals.
- Kaulava (कौलव): Excellent for friendship, partnerships, agreements, and romance.
- Taitila (तैतिल): Ideal for architecture, construction, and public works.
- Gara (गर): Recommended for agricultural planting, cattle care, and grounding efforts.
- Vanija (वणिज): Highly auspicious for retail, trade, financial transactions, and investments.
- Vishti / Bhadra (विष्टि / भद्रा): A period where new ventures, travels, and marriages are traditionally paused; ideal for protective rituals, dismantling negative influences, and legal defense.
The 4 Fixed Karanas (occurring once per month at the conclusion of the dark half):
- Shakuni (शकुनि): 2nd half of Krishna Chaturdashi.
- Chatushpada (चतुष्पद): 1st half of Amavasya.
- Naga (नाग): 2nd half of Amavasya.
- Kinstughna (किंस्तुघ्न): 1st half of Shukla Pratipada.
1.5 Var (The Solar Weekday & Planetary Hour)
The fifth limb is the Var (solar weekday), which runs from local sunrise to the following sunrise. Each day is governed by a ruling planet (Vara Lord) that infuses the day with distinct vibrational qualities:
- Ravivar (Sunday): Sun (Surya) — Leadership, fatherly respect, health vitality, government dealings.
- Somvar (Monday): Moon (Chandra) — Mental peace, emotional healing, water activities, maternal matters.
- Mangalvar (Tuesday): Mars (Mangal) — Courage, engineering, sports, defense, resolving property debates.
- Budhavar (Wednesday): Mercury (Budha) — Trade, accounting, mathematics, writing, diplomacy.
- Guruvar (Thursday): Jupiter (Brihaspati) — Higher education, wisdom, legal counsel, spiritual pilgrimage, marriage ceremonies.
- Shukravar (Friday): Venus (Shukra) — Arts, music, jewelry, vehicle purchases, luxury, social festivities.
- Shanivar (Saturday): Saturn (Shani) — Discipline, charity to the underprivileged, real estate, meditation, long-term perseverance.
2. Bikram Sambat (BS) vs. Gregorian (AD): The Solar-Sidereal Difference
A major reason generic calendars fail Nepali users is the difference between tropical and sidereal solar calculations:
┌───────────────────────────────────────┬───────────────────────────────────────┐
│ BIKRAM SAMBAT (BS) SYSTEM │ GREGORIAN (AD) SYSTEM │
├───────────────────────────────────────┼───────────────────────────────────────┤
│ • Solar-Sidereal (Nirayana) Base │ • Solar-Tropical (Sayana) Base │
│ • Anchored to Solar Ingress (Sankranti)│ • Fixed mathematical month lengths │
│ • Months range from 29 to 32 days │ • Months are fixed at 28 to 31 days │
│ • Leap adjustments via celestial entry │ • Leap day added every 4 years (Feb 29)│
│ • Tracks true constellation positions │ • Slowly drifts relative to the stars │
│ • Approximately 56.7 years ahead │ • Standard civil global calendar │
└───────────────────────────────────────┴───────────────────────────────────────┘
In the Bikram Sambat system, a new month begins on the exact day the Sun transitions from one zodiac sign into the next—a celestial event known as Sankranti (e.g., Mesha Sankranti on Baisakh 1, Makar Sankranti on Magh 1). Because the Earth's orbit is elliptical, the Sun appears to move faster near perihelion (January) and slower near aphelion (July). As a result, Nepali months vary organically between 29, 30, 31, and 32 days, requiring precise astronomical tables rather than fixed arithmetic.
3. How to Pick Auspicious Timings: Choghadiya, Hora & Rahu Kaal
Vedic timekeeping is deeply practical. Ancient sages recognized that different portions of the day carry distinct energetic potentials. Sripatro computes three primary daily Muhurat frameworks:
3.1 24-Hour Choghadiya Muhurat
A Choghadiya divides the daytime (sunrise to sunset) into 8 equal parts and the nighttime (sunset to sunrise) into 8 equal parts (each approximately 1.5 hours, though changing with seasonal daylight):
- Amrit (अमृत): Best for all auspicious beginnings, health treatments, and sacred ceremonies.
- Shubh (शुभ): Auspicious for marriages, educational pursuits, and religious rites.
- Labh (लाभ): Ideal for commerce, new financial investments, and starting businesses.
- Char (चल): Favorable for journeys, vehicle travel, and dynamic tasks.
- Udveg (उद्वेग): Ruled by the Sun; prone to anxiety, avoid gentle negotiations.
- Kaal (काल): Ruled by Saturn; suitable for cleanup, avoid joyful investments.
- Rog (रोग): Ruled by Mars; prone to conflicts and illness, avoid major celebrations.
3.2 Planetary Hora System
The Hora system divides every 24-hour day into 24 planetary hours, starting with the ruler of that weekday at local sunrise. For example, on a Sunday (Ravivar), the 1st hour is Sun Hora, the 2nd is Venus Hora, the 3rd is Mercury Hora, the 4th is Moon Hora, the 5th is Saturn Hora, the 6th is Jupiter Hora, and the 7th is Mars Hora. Selecting the right Hora for targeted activities (e.g., Jupiter Hora for studying or Mercury Hora for trading) optimizes results.
3.3 Rahu Kaal, Yamaghanta & Gulika Kaal
Every day contains specific windows ruled by shadowy astronomical nodes:
- Rahu Kaal (राहुकाल): An approximate 90-minute window each day where new worldly beginnings, signing contracts, and departures for long journeys are traditionally deferred.
- Yamaghanta (यमघण्ट): Associated with death and delays; avoided for auspicious celebrations.
- Gulika Kaal (गुलिक काल): Ruled by the son of Saturn; highly recommended for constructive long-term tasks and buying permanent assets.
4. Sripatro's Technological Edge: Authentic Precision & Zero-Knowledge Privacy
Unlike traditional paper almanacs (Patros) that were published for a single central city (like Kathmandu or Varanasi) and suffered geographical distortion across eastern, western, or diaspora locations, Sripatro solves key modern challenges:
- Exact Geolocation Coordinates: Calculates sunrise, sunset, Tithi cusps, and ascendant degrees precisely for your latitude, longitude, and elevation.
- Offline-First PWA Technology: Access daily Panchang, calendar conversions, and saved horoscopes even in remote Himalayan valleys with intermittent internet.
- Zero-Knowledge Architecture: Your sensitive birth date, time, and coordinates are processed locally in your browser and never sold or stored in tracking databases.
5. Frequently Asked Questions (FAQs)
Q1: Why does a Tithi sometimes span across two civil calendar days?
A Tithi is measured strictly by the 12° angular separation between the Sun and Moon. If a Tithi starts in the afternoon of Monday and concludes on Tuesday afternoon, it spans both civil days. In Vedic tradition, the Tithi present at the moment of local sunrise (Udaya Tithi) is generally adopted as the primary Tithi for religious observances and fasting (Vrata).
Q2: What is the difference between Shukla Paksha and Krishna Paksha?
Shukla Paksha is the bright waxing phase (New Moon to Full Moon) symbolizing growth, expansion, and initiation. Krishna Paksha is the dark waning phase (Full Moon to New Moon) symbolizing introspection, completion, and spiritual cleansing.
Q3: How do I know which Naam Akshar to give my newborn?
When a baby is born, note their exact birth time to compute the active Moon Nakshatra and Pada (quarter). Each of the 108 Padas across the 27 Nakshatras corresponds to a specific Sanskrit phoneme (e.g., Chu, Che, Cho, La for Ashwini). Sripatro's Naam Akshar & Daily Panchang tool automatically calculates this for you.
Conclusion
The Nepali Panchang is far more than a calendar—it is an intricate cosmic map connecting human life with celestial harmony. By understanding the five limbs of time, observing auspicious Muhurats, and honoring cultural milestones with astronomical accuracy, we bring balance, clarity, and intention to every day.
