Cast your reading
The name on your birth certificate and the date you arrived. That is all numerology has ever needed — no birth time, no location, no questionnaire.
If another calculator gave you a different Life Path
Three classical methods work a Life Path — adding every digit of the date straight across, reducing the month, day and year first, or reducing them while keeping any master number intact — and on about one birth date in six they disagree. The same date can be an 11 under two of them and a 2 under the third.
Most calculators pick one silently, which is why people are handed two different numbers and assume somebody made a mistake. We run all three. When they agree you see one number; when they disagree we lead with the master reading, write it in the 11/2 form, and print all three workings so you can see exactly where the split happens and judge it yourself.
