Built to hold up under scrutiny.

Most numerology and astrology sites online skip the parts that are actually hard to get right. Master numbers get flattened, moon phases get pulled from a generic feed instead of calculated, and every reading somehow lands exactly flattering. Sundial House exists because that bar felt too low.

Every calculator here is fact-checked against more than one source, shows its own arithmetic instead of hiding it behind a black box, and includes the parts of a reading that aren't flattering along with the parts that are. Nothing is stored — no accounts, no birth data kept anywhere — because you shouldn't have to trust a stranger's server to get an honest answer.

This isn't written for one type of visitor. It holds up for people who think the whole thing is nonsense and just want the math to be right, and it goes deep enough for people who've been doing this for years and can tell within a sentence whether something was actually researched.

Sundial House is built and maintained by one person — no team of horoscope writers, no templated content mill. If something here is wrong, it gets fixed by someone who actually checked it, not quietly left as-is.
