Your age is more than just years—you’ve lived months, weeks, and days that tell your story. Our Age in Days/Weeks/Months Calculator helps you discover your age in complete detail. Whether you’re celebrating a milestone or planning life events, this precise calculator makes it easy. Enter your date of birth and, if needed, any future date, to see how much time has passed in all time units.

• ⏳ Reflect on time lived with precise breakdowns.
• 📘 Useful for teachers creating date-based lessons or birthdays.

How To Use It

1. Choose your date of birth.

How It Works

The calculator computes the difference in milliseconds between two dates, converts that into days, then calculates weeks (÷7), months (÷30), and years (÷12 months). While these approximations may differ slightly from calendar months, they offer clear insight into time passed.

Practical Uses & Applications

• ✅ Parents tracking a baby’s exact milestones at 100 days, 50 weeks, etc.
• 💼 HR professionals calculating tenure or service durations.
• 🎂 Planning birthday surprises based on exact age days.
• 🧓 Seniors checking benefits eligibility like 80+ years.

Limitations

• This version estimates months as 30 days and weeks as 7 days—calendar months may slightly vary (28–31 days).
• For precise calendar-based calculations, use a date diff library or tool.
• Date order matters: ensure the “as of” date is after your DOB.
