Formula Used in Birth Star Calculation
This tool uses a combination of calendar-based logic and modular arithmetic to generate results.
1. Birth Day Calculation
The day of the week is calculated using JavaScript’s built-in date system:
Birth Day = Day Index from Date Object
Where:
- 0 = Sunday
- 1 = Monday
- 2 = Tuesday
- 3 = Wednesday
- 4 = Thursday
- 5 = Friday
- 6 = Saturday
This maps your date directly to a weekday name.
2. Zodiac Sign Calculation
Zodiac signs are determined based on birth month mapping:
| Month | Zodiac Sign |
|---|---|
| January | Capricorn |
| February | Aquarius |
| March | Pisces |
| April | Aries |
| May | Taurus |
| June | Gemini |
| July | Cancer |
| August | Leo |
| September | Virgo |
| October | Libra |
| November | Scorpio |
| December | Sagittarius |
This simplified system assigns one zodiac sign per month.
3. Birth Star (Nakshatra) Calculation
Nakshatras are calculated using a modular formula:
Nakshatra Index = (Day of Month + Month Index) % 27
Then the result is mapped to one of 27 Nakshatras:
- Ashwini
- Bharani
- Krittika
- Rohini
- Mrigashira
- Ardra
- Punarvasu
- Pushya
- Ashlesha
- Magha
- Purva Phalguni
- Uttara Phalguni
- Hasta
- Chitra
- Swati
- Vishakha
- Anuradha
- Jyeshtha
- Mula
- Purva Ashadha
- Uttara Ashadha
- Shravana
- Dhanishta
- Shatabhisha
- Purva Bhadrapada
- Uttara Bhadrapada
- Revati
This provides a symbolic Nakshatra result based on simplified computation.
