Vedic Zodiac Dates: Sidereal Rashi Calendar
Did you know your Vedic zodiac sign might be different from your Western sign? Vedic astrology uses the sidereal zodiac (Nirayana chakra), which aligns with actual constellations in the sky. Because of a phenomenon called the precession of the equinoxes (slow shifting of Earth’s axis), the Vedic zodiac is currently about 23–24 degrees behind the tropical zodiac used in Western astrology.
If you want authentic Vedic insights, you need accurate Vedic astrology zodiac dates. This guide provides a complete sidereal Rashi (zodiac sign) calendar, explains how the dates are calculated, and helps you find your true Sun sign and Moon sign within the Vedic framework.
Sidereal vs Tropical Zodiac: A Quick Comparison
- Tropical zodiac (Western) anchors Aries to the spring equinox on March 21 each year, ignoring the shift of constellations.
- Sidereal zodiac (Vedic) measures signs based on fixed star constellations, adjusting for the precession drift.
- Result: Most people discover their Vedic Sun sign shifts one sign backward compared to their Western sign unless their birthday falls near the start/end boundary.
Vedic Zodiac Dates (Sidereal Rashi Calendar)
Note: Dates can shift by a day depending on the year and location. Always verify with an accurate Panchanga (Vedic calendar) or chart calculator for precision.
| Rashi (Sign) | Sanskrit Name | Symbol | Approximate Sidereal Dates* |
|---|---|---|---|
| Aries | Mesha | Ram | April 13 – May 14 |
| Taurus | Vrishabha | Bull | May 15 – June 14 |
| Gemini | Mithuna | Twins | June 15 – July 16 |
| Cancer | Karka | Crab | July 17 – August 16 |
| Leo | Simha | Lion | August 17 – September 16 |
| Virgo | Kanya | Maiden | September 17 – October 17 |
| Libra | Tula | Scales | October 18 – November 16 |
| Scorpio | Vrischika | Scorpion | November 17 – December 16 |
| Sagittarius | Dhanu | Archer | December 17 – January 14 |
| Capricorn | Makara | Sea Goat | January 15 – February 12 |
| Aquarius | Kumbha | Water Bearer | February 13 – March 14 |
| Pisces | Meena | Fish | March 15 – April 12 |
*Dates derived from Lahiri ayanamsa, the most widely used sidereal correction in India.
How to Find Your Vedic Sun Sign
- Locate your birthday in the table above.
- If your birthday is within 1 day of the boundary, use a Vedic chart calculator with your birth time and place for accuracy.
- Remember that the Vedic day can start at sunrise, so people born around midnight may fall into the previous date range depending on the city.
Moon Sign (Chandra Rashi) Matters More
While Western astrology emphasizes the Sun sign, Vedic astrology prioritizes the Moon sign (Chandra Rashi) because it reflects your mind, emotions, and daily experiences. To find it:
- Use a trusted Kundli calculator (such as VedicGod’s free birth chart tool).
- Enter your exact birth date, time, and location.
- Note the Moon’s sign—this is the Rashi used for horoscopes, compatibility, and Dasha (planetary period) predictions.
Nakshatra Calendar Snapshot
Each Rashi spans 2–3 Nakshatras (lunar mansions). Knowing your Nakshatra gives even more precise guidance:
- Mesha (Aries): Ashwini, Bharani, Krittika (first part)
- Vrishabha (Taurus): Krittika (last part), Rohini, Mrigashira (first part)
- Mithuna (Gemini): Mrigashira (last part), Ardra, Punarvasu (first part)
- …and so on through 27 Nakshatras.
Nakshatras help you understand personality traits, compatibility, and favorable timings for life events.
Why the Dates Shift Over Time
The precession of the equinoxes causes the tropical zodiac to drift about 1 degree every 72 years. Vedic astronomers developed Ayanamsa (sidereal correction) to account for this. The Lahiri ayanamsa value for 2025 is approximately 24°07′, meaning Vedic signs start about 24 degrees before Western signs.
Example: If your tropical Sun is at 18° Taurus, subtract 24° → -6° Taurus, which wraps into 24° Aries. So, your Vedic Sun sign becomes Aries (Mesha).
Practical Uses of the Sidereal Rashi Calendar
- Daily Panchanga planning: Align activities with favorable Tithi (lunar day), Nakshatra, and Rashi.
- Horoscope reading: Check weekly or monthly predictions based on Moon sign rather than Sun sign.
- Compatibility analysis: Use Moon sign and Nakshatra to evaluate partnership harmony.
- Seasonal rituals: Festivals like Makar Sankranti (Sun entering Capricorn) use sidereal dates.
Frequently Asked Questions
Do I have to change my entire identity if my Vedic sign is different?
Think of the Vedic sign as an additional layer of self-awareness. Many people resonate with both signs in different ways. Use whichever system helps you grow.
Why do some websites show slightly different dates?
They may use a different ayanamsa (e.g., Raman, Krishnamurti). Lahiri is the Indian government standard, so we recommend it for consistency.
Can I follow Western and Vedic horoscopes together?
Absolutely. Western astrology emphasizes psychological themes (Sun sign), while Vedic astrology offers predictive accuracy (Moon sign, Dasha cycles). Combining both gives a holistic view.
How do I get my full Vedic chart?
Use a reliable Kundli generator that provides planets, houses, Nakshatras, and divisional charts. Many tools also supply a daily Panchanga and Dasha timeline.

Month-by-Month Rashi & Festival Guide
The sidereal zodiac also shapes the Indian lunar-solar calendar. Here’s a quick overview linking each Rashi to the traditional solar month and key festivals:
| Rashi | Solar Month | Approx. Gregorian Dates | Major Observances |
|---|---|---|---|
| Mesha (Aries) | Chaitra | Apr 13 – May 14 | Chaitra Navratri, Ram Navami |
| Vrishabha (Taurus) | Vaishakha | May 15 – Jun 14 | Akshaya Tritiya, Buddha Purnima |
| Mithuna (Gemini) | Jyeshtha | Jun 15 – Jul 16 | Ganga Dussehra, Nirjala Ekadashi |
| Karka (Cancer) | Ashadha | Jul 17 – Aug 16 | Guru Purnima, Rath Yatra |
| Simha (Leo) | Shravana | Aug 17 – Sep 16 | Raksha Bandhan, Krishna Janmashtami |
| Kanya (Virgo) | Bhadrapada | Sep 17 – Oct 17 | Ganesh Chaturthi, Pitru Paksha |
| Tula (Libra) | Ashwin | Oct 18 – Nov 16 | Sharad Navratri, Dussehra |
| Vrischika (Scorpio) | Kartik | Nov 17 – Dec 16 | Diwali (varies), Kartik Purnima |
| Dhanu (Sagittarius) | Margashirsha | Dec 17 – Jan 14 | Gita Jayanti, Dhanu Sankranti |
| Makara (Capricorn) | Pausha | Jan 15 – Feb 12 | Makar Sankranti, Pongal |
| Kumbha (Aquarius) | Magha | Feb 13 – Mar 14 | Maha Shivaratri, Magha Purnima |
| Meena (Pisces) | Phalguna | Mar 15 – Apr 12 | Holi, Phalguna Purnima |
These alignments help you plan rituals, fasts, and temple visits with true sidereal timing instead of approximations.
Converting Western Placements to Vedic (Step-by-Step)
- Note the tropical longitude of the planet from a Western astrology chart (e.g., Sun at 23° Leo).
- Obtain the ayanamsa value for the date—Lahiri ayanamsa tables or apps display the exact degree-minute-second offset.
- Subtract the ayanamsa from the tropical longitude. If the result drops below 0°, wrap around by adding 360°.
- Identify the sidereal sign by checking which 30° segment the adjusted value falls into.
- Record precise degrees for advanced analysis (e.g., 29° Leo tropical − 24° ayanamsa = 5° Cancer sidereal).
Most chart software handles this automatically, but practicing a few manual conversions builds trust in the system.
Understanding Different Ayanamsa Systems
While Lahiri is the Indian standard, you might encounter alternative ayanamsa options:
- Raman: Slightly smaller correction; used by some South Indian astrologers.
- Krishnamurti: Popular in KP astrology; optimized for predictive timing.
- Fagan-Bradley: Western sidereal school; differs by ~1° from Lahiri.
- True Lahiri (Chitrapaksha): Updates the correction continuously with astronomical measurements.
When comparing charts from different sources, check the ayanamsa setting to avoid confusion. Consistency is more important than picking the “perfect” value.
Handling Time Zone & Location Nuances
- Birth near midnight: The sidereal day starts at sunrise, so births between midnight and sunrise may belong to the previous date according to traditional Panchangas. Cross-reference with software to confirm.
- Daylight saving adjustments: Enter the local time exactly; chart calculators automatically subtract DST when configured correctly.
- Southern Hemisphere: The sidereal zodiac remains the same worldwide, even though seasons flip. Focus on planetary positions, not weather metaphors.
If your birth certificate lists an ambiguous time, ask relatives or use life-event-based rectification to refine the chart.
Cusp Births & Double-Check Strategy
People born when the Sun or Moon hovers around 0° or 29° need extra verification:
- Generate charts using two reliable calculators (e.g., AstroSage + Jagannatha Hora).
- Compare planetary degrees; if they match within minutes, you’re in the clear.
- Read descriptions of both potential signs—note which traits, dashas, and transits resonate more.
- Observe real-life events (career boosts, relationships, relocations) and match them with transit effects to confirm the correct sign.
Journaling these observations for 3–6 months usually reveals the accurate placement.
Rashi Flashcards for Quick Learning
Create 12 flashcards (digital or paper) with:

- Highlight supportive activities: For instance, when the Moon transits Taurus (Vrishabha), plan nourishing meals, gardening, or finance reviews.
- Track emotional trends: Log how you feel under each Moon sign to build your personalized lunar diary.
- Schedule rituals: Align mantra chanting, fasting, or meditation with the sign’s natural strengths (e.g., Kumbha Moon for community service).
Within a month, you’ll notice reliable patterns that make planning effortless.
Frequently Asked Questions (Advanced)
How does the sidereal zodiac impact career astrology?
Career yogas rely on accurate house placements and planetary dignity. Using sidereal dates ensures your 10th house lord, dashas, and divisional charts reflect the true sky, leading to precise timing for promotions or job changes.
What about lunar months (Chandra Maas)?
Lunar months begin on the new Moon (Amavasya). Their names stay in sync with the Sun’s sidereal position—when the Sun enters Dhanu, the lunar month becomes Margashirsha. Tracking both systems lets you plan fasting, weddings, and pilgrimages more accurately.
Can I mix sidereal Sun sign with tropical rising sign?
Mixing systems creates confusion. Choose one zodiac (sidereal or tropical) for all calculations so your house cusps and planetary aspects remain consistent.
Why do some Panchangas list slightly different transition times?
Astronomical software may round to different decimal places or use varied ephemerides. The difference is usually a few minutes. For important rituals, consult a trusted local priest or astronomer who accounts for your precise longitude and latitude.
