How It Works? (Basic Calculator)
Compute in Y/M/D format:
- Calculate full years between the two dates.
- Calculate remaining full months.
- Calculate remaining days.
(Real calculations use actual calendar month lengths.)
Compute in total days:
- Count all days including leap years exactly.
Convert to hours/minutes/seconds:
Turns days into smaller units; these are approximate since they assume consistent day lengths (e.g., no leap seconds).
Age Comparison Calculator
An Age Comparison (or Age Difference) Calculator measures the difference between two people’s birthdays. It computes:
- The age gap in complete years (e.g., 5 years older).
- The precise difference in years, months, and days
- Optionally, the difference in years, months, and total days. With customized name options.
- Common use cases include siblings, partners, friends, or any two individuals.
Life Milestone Tracker
A Life Milestone Tracker helps individuals record and reflect on significant events throughout their life- birthdays, anniversaries, graduations, goals achieved, personal development moments, and more. Here’s a comprehensive breakdown of its utility, features, and implementation ideas for MasterCalculator.in.

Frequently Asked Questions (FAQs): Age Calculator
Q1. What does the Age Calculator compute?
This tool determines your precise age from birth to today or another selected date in years, months, and days. You can also see your age in hours, minutes, or total days.
Q2. How accurate is age calculator?
Very. It takes leap years and varying month lengths into account, using a reliable algorithm to ensure exact age calculations.
Q3. Can I calculate future age in the age calculator?
Yes, you can any future (or past) date to find out how old you will be (or were) on that day.
Q4. Why do months sometimes equal 30.44 days?
For single-unit results (like “months only”), some calculators use average month lengths (~30.4375 days) or an average year (=365.25 days). Our primary output uses exact calendar values, accounting for real month lengths and leap years.
Q5. Do leap years affect the calculation?
We automatically include February 29 in age computations and follow Gregorian rules: years divisible by 4 are leap years except those divisible by 100 but not 400.
Q6. What if I only enter a birth year?
If you enter just a year, the calculator estimates your age based on that year’s beginning (or ending) but may be off by several months. For precise results, always provide the full birth date.
Q7. What is “completed age vs. running age”?
Completed age = full years that have passed (e.g., 25 until your 26th birthday)
Running age = your current year of life (e.g., 26th year at age 25)
Our calculator shows completed age in years, months, and days for clarity.
