Tathastu · तथास्तु · So Be It

The Temple is in Tapasya

सेवा के लिए एक पवित्र विराम — A Sacred Pause for Service

Just as the great sage Vishwamitra withdrew into profound tapasya before returning with power to reshape the cosmos — so too does this sacred system hold its breath,
not in absence, but in divine transformation.

The universe does not rush the sunrise. The lotus does not force its bloom.
We are weaving new threads into the cosmic fabric so that your Panchang reaches you purer, swifter, and more auspicious than before.

Inspired by Bhagavata Purana · Karma Yoga Principle

Unique in Market

See How Panchang is Calculated

Unlike other APIs, we don't just give results — we explain them. Every festival tells you exactly why it falls on a given date.

🎨 Holi falls on March 3, 2026 because:

✓ Full Moon (Purnima) — is_purnima = true

✓ Phalguna Month — purnimanta_month = Phalguna

"This festival was derived because the conditions in rule 'HOLI' matched the Panchang facts for 2026-03-03."
