Frequently Asked Questions
How is age calculated exactly? ▼
Age is calculated by finding the difference between your date of birth and today (or any specified date). The tool counts complete years first, then remaining months, then remaining days. Hours and minutes are calculated from the total milliseconds elapsed since your birth moment (assuming midnight on your birth date).
Why does my age differ by one day sometimes? ▼
Age calculations depend on the exact time of day. Since most people don't know their birth time, this calculator assumes midnight (00:00) on your birth date. If your birthday is today, you may appear one year older depending on the time of day.
Can I calculate age as of a specific past or future date? ▼
Yes. Use the optional "Calculate Age On" date field to specify any past or future date. This is useful for legal purposes (calculating age at a specific event), historical research, or finding out your age at a future milestone.
What is a zodiac sign and how is it determined? ▼
Your zodiac (star) sign is determined by the calendar date you were born. The 12 zodiac signs each cover a range of dates: Aries (Mar 21–Apr 19), Taurus (Apr 20–May 20), Gemini (May 21–Jun 20), Cancer (Jun 21–Jul 22), Leo (Jul 23–Aug 22), Virgo (Aug 23–Sep 22), Libra (Sep 23–Oct 22), Scorpio (Oct 23–Nov 21), Sagittarius (Nov 22–Dec 21), Capricorn (Dec 22–Jan 19), Aquarius (Jan 20–Feb 18), Pisces (Feb 19–Mar 20).
Is my birth date stored or shared? ▼
Never. All calculations happen locally in your browser. Your date of birth is never sent to any server, stored, or shared. See our Zero Data Storage Policy.
