Do I need my birth time?
Usually not — the Moon spends about two and a half days in each sign, so most dates land safely in one sign. If you were born on a day the Moon changed signs, the hour decides; add it if you have it.
What does my moon sign actually describe?
Your emotional grammar: how feelings arrive, what safety feels like, what you reach for when the day has been too much. It is often the placement people recognize themselves in most deeply.
Is this computed or copied from tables?
Computed. Your birth data runs through the same self-hosted astronomical engine that powers our readings — with historical time-zone handling for your birthplace and year.
