Chandrashtama

Chandrashtama (Chandrashtama) — the transiting Moon's position in the eighth sign of the zodiac, counting from the sign the Moon stood in at the person's birth: traditionally an unfavourable personal lunar time. The name comes from the Sanskrit "chandra" (Moon) + "ashtama" (eighth). This is a personal factor — it is not tied to the Moon's general course through the sky, but to a specific person's birth chart.

Place in the system

Lunar factors describe states that depend on the Moon's position relative to a person's natal data. Chandrashtama begins when the transiting Moon enters the eighth sign from the sign of the natal Moon (the natal Moon's own sign counts as the first). In the count of Chandra Bala by signs from the janma-rashi, Chandrashtama is exactly this eighth position; it received a separate name because of its traditionally unfavourable reading. The transiting Moon stays in one sign for a little over two days, and the current Chandrashtama stretches over roughly that span; it recurs about once every 27–28 days — one circuit of the Moon around the zodiac.

Chandrashtama is a system separate from Tara Bala: that one counts the Moon's position by nakshatras from the birth nakshatra, while Chandrashtama counts by zodiac signs from the birth sign. Both factors are personal and both check the current Moon against the moment of birth, but they rest on different units of count; Chandrashtama can coincide even with a favourable tara and is not identical to any of the nine taras.

Practical meaning

Chandrashtama is a day of caution. Tradition cautions against important worldly undertakings: travel, trade matters, a wedding, laying a foundation. But it is not an "absolutely bad" day — it suits spiritual practice, fasting, purification.

The Chandrashtama background works through obstacle. It is a day on which the usual paths can be closed, and you need to look for a way around.

In Indian folk practice, Chandrashtama is a day of fasting and offerings to ancestors, a day of quiet practice. Many devout Hindus do not undertake major worldly matters on this day.

In daily practice

Chandrashtama is a day of quiet. If you have a choice, don't plan important worldly undertakings for this day. Better to spend it in fasting, prayer, meditation.

Chandrashtama also suits offerings to ancestors: tarpana, a memorial prayer. Tradition holds such days especially conducive to remembering ancestors.

Chandrashtama also suits a practice of letting go: releasing what holds you, not starting anything new, being modest in your wants. Tradition holds that this day teaches inner freedom.

Chandrashtama is personal by construction: it is calculated only when the natal Moon is known, and cannot be determined without birth data — unlike the day's tithi or nakshatra, which are the same for everyone. For a fuller picture, it's worth checking it against Tara Bala from the birth nakshatra: both factors speak to the personal vulnerability of the moment, but are calculated independently of each other and need not coincide.

Do not confuse with

Not to be confused with Vipat Tara — the third tara in the Tara Bala system: it too is unfavourable and personal, but is counted by nakshatras from the birth nakshatra, not by signs. The two factors often diverge in date and don't substitute for each other: Chandrashtama isn't a nakshatra system at all — its unit of count is the zodiac sign.
