What is Rashi and Nakshatra in Astrology?
Before using the calculator, it is important to understand what Rashi and Nakshatra mean.
🌙 What is Rashi (Moon Sign)?
Rashi refers to the zodiac sign in which the Moon was placed at the time of your birth. There are 12 Rashis in Vedic astrology:
- Aries (Mesha)
- Taurus (Vrishabha)
- Gemini (Mithuna)
- Cancer (Karka)

- Virgo (Kanya)
- Libra (Tula)
- Scorpio (Vrishchika)

The Moon sign is considered more important than the Sun sign in Vedic astrology because it represents your emotions and inner self.

Nakshatra means “lunar mansion” or star cluster. The Moon travels through 27 Nakshatras during its orbit around the Earth.
Some of the main Nakshatras include:

Formula Used in Rashi Nakshatra Calculation
This tool uses a simplified algorithm based on time and longitude to estimate astrological positions.
🌙 Rashi Calculation Formula
Rashi Index = |(Birth Hour + Longitude) mod 12|
Then:
Rashi Sign = signs[Rashi Index]
⭐ Nakshatra Calculation Formula
Nakshatra Index = |(Birth Minute + Longitude) mod 27|
Then:
Nakshatra = nakshatraList[Nakshatra Index]
📌 Zodiac Index Output
Zodiac Index = Rashi Index – Nakshatra Index
This helps display combined astrological positioning.
Example Calculation
Let’s understand how the calculator works with an example:
- Date of Birth: 10 June 1995
- Time of Birth: 14:30 (2:30 PM)
- Longitude: 72.5
Step 1: Rashi Index
Hour = 14
Formula: (14 + 72.5) % 12 = 10.5 → 10
Rashi = Capricorn (Makara)
Step 2: Nakshatra Index
Minute = 30
Formula: (30 + 72.5) % 27 = 102.5 % 27 = 21
Nakshatra = Uttara Ashadha
