Overview

About Cosmic Birthtime

Cosmic Birthtime is an online birth-time rectification service. Enter your birth date and city, an approximate birth-time window, and significant events such as marriages, relocations and career changes. If an exact event date is unavailable, a month and year can still be entered. Progress can be saved while you gather the details.

Its AI system, The Oracle, compares the information using astrological calculations and may ask clarifying questions. The result is a proposed birth time accompanied by a personalised PDF explaining how the estimate was reached.

Rectification is paid, currently listed at GBP 28 including the report. The service recommends a time window of two hours or less, and no more than four hours where possible. With no starting estimate, the result may cover a wider range. Cosmic Birthtime describes rectification as an estimation process and states that an exact minute cannot be guaranteed.

FAQ

What if I have no approximate birth time?

The service can work from life events, but says the estimate may cover a wider range. Its guidance recommends checking family or hospital records for a starting time window.

Do all life events need exact dates?

Specific dates are preferred. If the exact day is unknown, the form accepts a month and year, and progress can be saved while you gather information.

What does the payment include?

The current GBP 28 offer includes an estimated birth time and a personalised PDF explaining the analysis. The result remains an estimate.
