Numbers you can check

Dates of festivals depend on the exact moment a tithi begins and on sunrise. We compared the app with JPL DE421 over 5 cities and 17 years and published everything — method, errors found, and raw data.

Celestial horizon

The app uses the Celestial horizon, so that daytime equals night time — 12 hours each, 4 praharas each, as in CC Madhya 20.390. You can switch to the visible Earth-sky horizon in settings.
