Why amavasai matters

Tradition links amavasai with pitru rites, tarpanam, and quiet worship. This page is calendar reference, not ritual instruction. Follow your temple and family custom.

Why calendars disagree

Vakya vs Thirukanitha methods, sunrise-anchored days, and which civil date owns a tithi that spans two midnights - all create differences. Details: Vakya vs Thirukanitha

AstroYogam uses Thirukanitha + Lahiri + local sunrise (disc-center with refraction). Methodology: Methodology guide

Frequently asked questions

How is the Amavasai civil day decided?

Per Shastra (Dharma Sindhu), pitru tarpanam must be offered during Aparahna (mid-afternoon). The day Amavasya prevails during Aparahna is observed as Amavasai in South Indian tradition.

Why do two calendars show different dates?

Ayanamsa choice, Vakya vs Thirukanitha, and day boundary (sunrise vs midnight) can move the civil date.

Is this only for Chennai?

Yes - this page is for Chennai coordinates. Elsewhere, sunrise and sometimes the civil date shift. Set your location in the app.
