Leap Year & DST Proof

Calendar-pure algorithms protect your results from subtle daylight saving distortions and leap year bugs.

Age is calculated using astronomical calendar components: full completed years, remaining whole months, and remaining days.

In non-leap years, your birthday milestone is accurately celebrated on February 28, keeping age calculations consistent and deterministic.
