Accuracy & Limitations
While our durations are mathematically perfect, the calculation assumes the standard ISO calendar. It does not account for specific hour-of-birth timezone offsets unless explicitly entered (currently defaulting to 12:00 PM). This tool is intended for general informational purposes including retirement planning, school enrollment checks, and personal milestones.
