When to use this calculator
Use this tool when you have only a birth date and want a one-page overview instead of running separate calculators. It reports life path, birthday number and personal year together and links to the full guide for each.
How it is calculated
- Enter your birth date and the calendar year for the personal year.
- The tool calculates the life path from month, day and year.
- It calculates the birthday number from the day alone.
- It calculates the personal year from month, day and the chosen calendar year.
Worked example
Input: Born 29 November 1988, calendar year 2026
Working: Life path 3 (11 + 11 + 8 = 30, then 3). Birthday number 11 (2 + 9 = 11, a master number). Personal year 5 (11 + 11 + 1 = 23, then 5).
Result: Life path 3, birthday 11, personal year 5
Common mistakes
- Confusing the birthday number (day only) with the life path number (full date).
- Using today’s date as the birth date.
- Treating the personal year as lasting from birthday to birthday; this tool uses the calendar year.
