Lunar Phases and Astrological Importance

In the Tamil calendar, each month begins with Chithirai Nakshatra, aligning with the moon’s luni-solar cycles. The starting date of 2025 – April 14 reflects favorable planetary positions, especially Putrakanda Kalam (auspicious fortnight for new beginnings), making it ideal for new ventures, weddings, and spiritual ceremonies.

Tamil astrologers advise aligning important life events with this period to harness positive energy flowing from Rahu and Ketu transit, central to Vedic and Tamil astrology.

  • Cultural Events: Extended family samskarahas (life-cycle rituals), street processions, dance dramas (kolams), and temple processions featuring deities carried on carriages.
