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: /guides/vakya-vs-thirukanitha-panchangam
AstroYogam uses Thirukanitha + Lahiri + local sunrise (disc-center with refraction). Methodology: /guides/methodology
Frequently asked questions
Is amavasai the sunrise label or the exact new-moon moment?
The tithi changes with Sun-Moon elongation. This table's civil date is whether that tithi prevails at Chennai sunrise - the almanac-style assignment.
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.
