Whether it’s for age calculation, project timelines, or any other time-related analysis, having a reliable Years and Days Calculator can be invaluable. In this article, we will provide you with a simple yet powerful calculator built using HTML and JavaScript.

**How to Use**

Using the Years and Days Calculator is straightforward. Enter the start and end dates in the provided input fields, click the “Calculate” button, and the result will be displayed. The calculator considers leap years and accurately calculates the time span in terms of years and remaining days.

**Formula**

The formula for calculating the difference between two dates in terms of years and days involves considering leap years and months’ variations. The precise formula is:

$Years=End Year−Start Year−(End Month<Start Month)$

$Days=End Day−Start Day+Days in End Month−Days in Start Month$

**Example**

Suppose we want to find the difference between January 1, 2022, and December 31, 2023.

$Years=2023−2022−(12<1)=1$

$Days=31−1+31−0=61$

So, the result would be 1 year and 61 days.
