Your original date isn’t touched: I ran every snippet here with TypeScript 7.0.2 and Node.js v22.22.2 in strict mode, so the printed results are … Read more >>
I was recently working on a feature that needed to sync date and time data across users in different time zones.

Counting days between dates in TypeScript takes one line: subtract the two getTime() values and divide by 86,400,000, the number of milliseconds in a day. Wrap it in Math.round() so a daylight saving shift can’t leave you with 13.96 days: In this tutorial, we’ll count the days between dates in TypeScript the safe way, from … Read more >>

While working on a recent feature that displayed important dates in a user-friendly format, I encountered an issue. The ISO date string, like “2025-07-04T00:00:00.000Z,” was showing up as July 3 instead of July 4 in the UI. At first, it seemed like a simple formatting issue, but it turned out to be a classic time … Read more >>
When I was working on a TypeScript project recently, I got a requirement to show dates from a system that sent me big numbers like 1623456789000. These numbers are called timestamps, and they represent a date and time, but in a format that’s hard to read. In this blog, I will show you how to … Read more >>

For example, a user might type “2025-02-30”, which is not even a real date or the used date format is not valid for the app’s date settings. These small issues can cause big problems if we don’t handle them properly. … Read more >>

The result is the gap in milliseconds, which you divide down to seconds, hours or days. Writing end – start directly won’t compile in TypeScript: In this tutorial, we’ll subtract dates in TypeScript step by step. … Read more >>
