🎂 Age Calculator
🔒 Sicher & Clientseitig
Pick a birth date and get exact age — years, months, and days — plus total days alive and how many days until the next birthday. Handy for visa forms, school cutoffs, and "how old will I be in 2030" curiosity.
How to use
- Pick your date of birth.
- Optional: change the target date (default is today). Useful for "How old will I be on July 4, 2030?" questions.
- Click Calculate. Age in years / months / days, total days alive, and days until the next birthday all show up.
The calculator handles month-end edge cases — a baby born on Jan 31 turns one month old on Feb 28 (or 29 in leap years), not Feb 31. Years are full Gregorian years; leap days are counted toward the day total.
