Precision Age Calculator & Birthday Countdown
Calculate your exact age in years, months, and days instantly. Includes a life summary (total weeks/hours) and a countdown to your next birthday.
How It Works

2. Select “Age At” Date (Optional) By default, the tool calculates your age as of today. However, if you want to know how old you was on a specific past event, or how old you will be on a future date (like the year 2050), you can change this date.
3. Calculate Click the “Calculate Age” button. The tool processes the time difference and displays three key sections:
- Exact Age: The standard breakdown (e.g., 25 Years, 3 Months, 2 Days).
- Next Birthday: A countdown showing the specific date and remaining days.
- Life Summary: A fun statistic block showing your age purely in weeks, total days, or hours.
Inputs

Output
Displays Age (Years/Months/Days), Next Birthday details (Day of week/Countdown), and Total Stats (Total Months, Total Weeks, Total Days, Total Hours).
Tool Description
The Precision Age Calculator goes beyond simple year counting. It provides a detailed breakdown of your age based on your Date of Birth and a specific Target Date (defaulting to today). It handles complex calendar logic—such as leap years and varying month lengths—to give you an accurate result in Years, Months, and Days. Additionally, the tool offers a "Life Stats" summary, showing how many total weeks, days, or hours you have lived. It also features a built-in Birthday Countdown, telling you exactly which day of the week your next birthday falls on and how many days are remaining until the celebration.
