Do you trust your panchang app? Curious how people pick Ekadashi/Diwali dates

Building Ashtadha (launching here soon) and trying to understand something:

How do you decide which panchang source is "correct" for your family?

Drik? Temple pandit? WhatsApp forward? 😅

I built a free app/site because my family never agreed. Uses Swiss Ephemeris + city-specific sunrise.

Would love to hear:

- Your city

- What you follow for vrats

- Whether lyrics (Chalisa, aartis) in the same app is useful or clutter

Maker here — happy to share early access if anyone wants to sanity-check 2026 festival dates.
