π Frequently Asked Questions
Are my dates saved or stored anywhere?
No. Your privacy is a top priority. All calculations are performed directly in your browser, and the dates you enter are never sent to our servers or stored anywhere.
How does the calculator handle leap years?
The calculator uses the date functions built into your browser's JavaScript engine, which correctly account for leap years and the varying number of days in each month to give you an accurate result.
Can I calculate the duration between any two dates?
Yes. While it's designed as an age calculator, you can enter any start date and end date to find the precise time duration between them. The tool ensures the "Date of Birth" is earlier than the "Age at Date of" for a valid calculation.

How to Calculate Age and Duration
Our tool is designed for maximum simplicity and power. The result is just a click away.
- Enter the Start Date: Use the first date picker to select the year, month, and day of birth (or the starting date for your calculation).
- Enter the End Date: The second date picker is for the date you want to calculate the age at. This field defaults to the current day but can be changed to any date.
- Click "Calculate Age": Press the button and the tool will instantly display the precise age in years, months, and days, along with a detailed summary of the total time passed.
The Logic Behind the Calculation
Calculating a precise age is more complex than it seems. Our tool uses a robust algorithm implemented in JavaScript that follows these logical steps:
- It first calculates the difference in years, months, and days, carefully adjusting for cases where the end date's month or day is earlier than the start date's. This ensures the "human-readable" age is correct.
- It then calculates the absolute time difference between the two dates in milliseconds.
- This millisecond value is then converted into the summary totals you see: total seconds, minutes, hours, days, and weeks. This provides a different perspective on the same duration of time.
Completely Private and Secure
Your date of birth is sensitive, personal information. At NexaPrep Tools, we believe you should never have to share it just to use a simple calculator. Our Age Calculator runs entirely on your local device. The dates you enter are processed by a script in your browser and are never sent to our servers. We do not log, store, or track any of the data you enter. Your privacy is 100% guaranteed, making our tool a safe and trustworthy choice for everyone.
