Enter the baby's details to see the Sun sign, Moon sign, and name number in both Chaldean and Pythagorean systems.
Looking up birth location & calculating Moon sign…
Each letter mapped to its Pythagorean (P) and Chaldean (C) value.
Enter the baby's name, date of birth, time of birth, and place of birth. The calculator looks up the birth location to accurately determine the Moon's position at that moment.
Determined purely from the date of birth. The Sun moves through one zodiac sign per month, so the date alone is enough to identify it.
The Moon changes sign roughly every 2.5 days, so both the time and place of birth matter. The calculator uses astronomical formulas (Jean Meeus) and your birth location's timezone to calculate the Moon's exact position.
Both systems assign a number to each letter and reduce the total to a single digit. Chaldean (used widely in Indian numerology) assigns values 1–8 based on sound; Pythagorean numbers the alphabet sequentially 1–9.
The Moon moves through a zodiac sign in about 2.5 days. Without the time, the Moon sign can be wrong by one sign for births near a transition.
No. All calculations run in your browser. The place is sent to OpenStreetMap (for coordinates) and TimeAPI (for timezone) — no personal data is retained.
For Indian names and traditions, Chaldean is most commonly used. Pythagorean is more popular in Western numerology. Many practitioners check both.
