About Leap Year Calculator

Understand leap years instantly -- check single years or analyze large year ranges with detailed insights.

How This Tool Works

The Leap Year Calculator determines whether a given year or range of years includes leap years. It follows the Gregorian calendar rules -- a leap year occurs every 4 years, except for years divisible by 100 unless they are also divisible by 400. The tool can handle both single-year checks and large range analyses efficiently.

Shows the percentage of leap years in a range.
Animated icons and color-coded results for better clarity.

Enter the desired year(s) in the input fields.
Click the “Check Year” or “Analyze Range” button.
View detailed results, including leap year count and percentage.
Use the clear button to reset inputs and try again.
