Hello Neha!
If you’re working with local times and want to account for things like daylight savings time (DST) or locale-specific differences, Intl.DateTimeFormat can come in handy.
Why use it?
Intl.DateTimeFormat is useful for displaying localized dates. While this doesn’t directly calculate differences, you can combine it with date difference methods to show localized time differences.
Example:
javascript
CopyEdit
const date1 = new Date('2025-05-01T00:00:00');
const date2 = new Date('2025-05-02T12:00:00');
// Format dates
const formatter = new Intl.DateTimeFormat('en-US', { month: 'short', day: 'numeric', year: 'numeric' });
console.log(formatter.format(date1)); // May 1, 2025
console.log(formatter.format(date2)); // May 2, 2025
Great little helper for international-friendly apps or when your users span multiple timezones!
