A nakshatra is one of 27 lunar mansions (or asterisms) used in Vedic astrology to track the Moon's position. The Moon travels through all 27 nakshatras in approximately 27.3 days — completing one full cycle each lunar month. Each nakshatra spans 13°20' of the zodiac and has its own deity, ruling planet, symbol, and quality. Nakshatras are considered more specific and personally meaningful than the 12 sun signs because the Moon represents the mind and the innermost self.

Your janma nakshatra is determined by the position of the Moon at the exact time and place of your birth. You can calculate it using a Vedic birth chart (kundali) calculator — you need your birth date, time, and location. Many Vedic astrology apps and websites offer free calculations. Your janma nakshatra is one of the most important factors in Vedic astrology — it governs your instincts, emotional nature, and the mantra most suited for your personal practice.

Each nakshatra has a ruling deity and planet that creates a specific energetic field when the Moon is transiting through it. Chanting mantras aligned with the day's nakshatra deity amplifies the mantra's potency — you are working with the cosmic current rather than against it. For example, when the Moon is in Rohini (ruled by the Moon, deity Vishnu), Vishnu mantras carry extra power. When the Moon is in Ardra (ruled by Rahu, deity Shiva), Shiva mantras are most potent.

There are 27 principal nakshatras in Vedic astrology, each spanning 13°20' of the ecliptic — totaling 360°. Some systems include a 28th nakshatra called Abhijit (corresponding to the star Vega), which is used in Muhurta (electional astrology) for its highly auspicious quality. The 27 standard nakshatras are what most Vedic astrologers use for daily transit analysis, birth chart interpretation, and choosing auspicious times for activities.

Rashi (zodiac sign) and nakshatra (lunar mansion) are two different coordinate systems in Vedic astrology. There are 12 rashis (30° each) and 27 nakshatras (13°20' each) — so each rashi contains 2.25 nakshatras. Rashi is primarily used for sun sign astrology and broad personality traits, while nakshatra provides more nuanced, emotionally specific information. In Vedic astrology, your Moon nakshatra (janma nakshatra) is generally considered more significant than your sun sign for understanding your inner life and spiritual path.
