Eight pieces on how the calculations work, one tradition at a time, each written from the app's own code and its own disclosures, including the parts that are a convention rather than a citation, and the parts that are missing.
Two computus algorithms, a thirteen-day offset that refuses to run outside the years it was calibrated for, and one feast derived by subtraction so it can never drift out of step.
The Shvetambar and Digambar parvas are not one date with a variant. They are separate tithi rules under one engine, and one parva is deliberately left unscoped.
Three observances, three texts, and a tradition tag that deliberately computes nothing. This is the thinnest dharma in the app, and the reasons are written down.
A deterministic daily draw from the app's own Gurbani corpus that always declines to answer the question you asked, and the reason comes from Gurbani itself.
Most people read a panchang for one line of it. Here is what all five parts measure, and how ZindSa arrives at them without asking a server.
They get used interchangeably and they are not the same thing. Each is derived differently, and one of them is not on a clock at all.
This is ZindSa's own methodology, written out in public, including the parts that are a convention rather than a citation.
Birth date, birth time, birth place. Three of the most identifying facts about a person, handed to an app. Here is exactly what ZindSa does with them, and what it does not claim.
