🎂 Age Calculator - Find Your Exact Age Instantly
Use this fast and modern Age Calculator to find your exact age in years, months, and days. Whether you're filling out official documents, planning milestones, or just curious, this tool gives you an accurate breakdown of your age based on any two dates - not just today.
✅ What You Can Do
- Calculate your current age by entering your birthdate (default is today).
- Find your age on any specific date - past or future - using the "Age at the Date of" option.
- Get a detailed breakdown - the result includes years, months, and days.
📘 Examples
- Born on Jan 1, 2000 — as of Jan 1, 2025 → 25 years, 0 months, 0 days
- Born on Dec 31, 1995 — as of Jun 16, 2025 → 29 years, 5 months, 16 days
🔍 How It Works
The calculator compares the selected "From" date (birthdate) and "To" date ("Age at the Date of") using native JavaScript Date objects. It performs a component-wise comparison:
- Subtracts the years directly from the two dates
- Adjusts months and days if the target day/month is earlier than the birthdate's
- Accounts for leap years and varying month lengths to keep the result accurate
💡 Tips for Best Results
- You can calculate future age by choosing a future date - useful for retirement planning or age eligibility checks.
- Want to know how old someone was on a historical date? Just enter that date in the second field.
- Refresh the page to reset both dates back to today quickly.
