Keep February 29 as the birth date
For a life path calculation, a February 29 birthday stays February 29. Do not substitute February 28 or March 1 based on when an annual celebration occurs. The tool uses the actual Gregorian birth date, including its year, and checks that the date exists.
These calculations follow numerology conventions; their interpretations are prompts for reflection, not scientific predictions.
A life path entry such as February 29, 1980 is valid because 1980 was a leap year. February 29, 1981 is not a valid calendar date. The form rejects an impossible date rather than moving it to a nearby day and quietly calculating a different input.
Work through the life path example
For February 29, 1980, the component method gives month 2, day 11 from 2 + 9, and year 9 from 1 + 9 + 8 + 0 = 18. Their sum is 22, retained as 22/4. The all-digits method gives 31, reducing to 4.
That difference comes from the master-number rule and reduction order, not from uncertainty about the leap day. You can compare both in the life path calculator. Keep the actual date unchanged when switching methods so you are comparing the algorithms rather than two birthdays.
A personal year uses numerical components
The personal year formula uses the birth month, birth day, and a selected calendar year. It does not construct an appointment date for the birthday in that year. February 29 is therefore accepted even when the target year is not a leap year.
For target year 2025, the birth month contributes 2. The day 29 reduces to 11 and then 2 because personal years do not retain master numbers here. The selected year reduces to 9. Add the parts: 2 + 2 + 9 = 13, then 4. The personal year result is 4 for the January–December 2025 period.
Do not confuse a celebration rule with a formula
Someone may celebrate on February 28 or March 1 in a non-leap year. That choice does not alter the birth month and day used by this calculator. A legal or administrative anniversary rule is also a separate question; this tool is not designed to determine deadlines or eligibility.
When comparing another numerology site, inspect whether it accepts the birth month and day as numbers or tries to create a date in the target year. Also check whether it uses calendar-year or birthday-to-birthday periods. The year-boundary guide explains that distinction.
Use the personal year calculator with the example first and open its working. A clear record lists the birth components, target year, reduction rule, and resulting period. Those details explain the calculation more reliably than treating a leap-day birthday as a reason to invent a special adjustment.
