What you need before you start
Before starting, confirm that dates, times, and other details are accurate, and note which items are required or optional. Do not replace missing required information with a guess.
Name
type in optional
Labels the profile so the result remains understandable and distinguishable.
Example: Alex
What to enter: Remove accidental extra spaces and enter only the information requested.
If you leave it out: The tool will continue with reduced detail and will not infer the missing value.
Birth date
date required
Establishes the calendar and timing data used by the calculation.
Example: 1990-06-15
What to enter: Use a valid calendar date that is not in the future.
If you leave it out: The tool cannot produce a reliable result without this required value.
Gender
choose optional
Applies method-specific rules and keeps the report wording appropriate.
Example: Female
What to enter: Choose one of the listed values; do not infer another person’s private information.
If you leave it out: The tool will continue with reduced detail and will not infer the missing value.
