How to compare two dates in JavaScript
Wednesday, October 1, 2025
Comparing dates is fundamental for validation, sorting, and implementing date-based business logic in web applications. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented date comparisons in countless components including calendars, data tables, and form validation. From my expertise, the most straightforward and reliable solution is to use standard comparison operators directly on Date objects. JavaScript automatically converts Date objects to timestamps for comparison, making this approach both simple and efficient.
