Checking if a date represents today is crucial for filtering real-time data, highlighting current records, and implementing time-sensitive UI features. As the creator of CoreUI with over 25 years of development experience, I’ve built this functionality into dashboard components, activity feeds, and data filtering systems countless times. The most reliable approach is comparing toDateString() values which automatically ignores time components while maintaining timezone consistency. This method eliminates the complexity of manual date component comparisons and time-related edge cases.
