⚙️ How It Works
The calculation subtracts the birth date from the current date. For years/months/days, we use a precise algorithm that counts full years, then remaining months, then days. For weeks, we divide total days by 7; for hours/minutes, total days × 24, etc. Timezone is based on your local browser time.
