What is Chandrashtamam?

Chandrashtamam (சந்திராஷ்டமம்) — literally "Moon in the 8th" — occurs when the Moon transits the 8th zodiac sign counted from your Janma Rashi (birth Moon sign). Since the Moon moves through all 12 signs in approximately 27.3 days, Chandrashtamam recurs roughly once a month and lasts about 2 to 2.5 days.

This period is considered inauspicious for starting new ventures, making major decisions, travel, or ceremonies. It is one of the most widely observed daily timing considerations in Tamil astrology and is listed in all traditional Tamil Panchangam calendars.

Remedies: Visit a Shiva temple, recite the Chandra Mantra (Om Som Somaya Namaha) 108 times, donate white items (milk, rice, silver), and observe a partial fast.

Avoid starting new businesses, signing contracts, making major financial decisions, long journeys, and surgery (non-emergency) during Chandrashtamam. Regular daily activities and ongoing work are generally unaffected.
How is Chandrashtamam calculated?
Chandrashtamam is calculated by tracking the Moon's sidereal position. When the Moon is in the 8th rashi from your Janma Rashi, that period is your Chandrashtamam. Thirukanitham uses the Drik (Thirukanitham) method aligned with the Lahiri ayanamsha.
