⏳ Time handling is one of those things you don’t realize is complicated until you actually try to code it. Over the years, I found myself stuck dealing with business day calculations, time zone weirdness, and more than a few edge cases in my projects. Eventually, I got tired of hunting for a clean, simple solution, so I decided to build one for myself.
👋 I’m the person behind Pastetime.com, which is just a collection of free tools to help you do things like:
- 🗓️ Figure out the number of business days between two dates, including custom weekends and holidays
- 🌍 Convert between UTC and your local time (or any city you want)
- 🔄 Translate timestamps between formats (ISO, Unix, RFC 2822, etc.)
I wanted something that was quick, easy, and didn’t push you to sign up or buy anything. Plus, it had to work on both desktop and mobile. So I made it for myself, and now it’s out there for anyone who needs it.
🚀 What Can You Do on Pastetime.com?
🗓️ Business Days Calculator
Get the number of business days between any two dates, no matter your region’s weekend or your company’s holiday schedule. You can set which days count as weekends, add any holidays you like, and see an instant answer.

🌐 UTC to Local Time Converter
Paste in any timestamp—ISO 8601, Unix, or RFC 2822—and see what time that actually is in your location or another city. It’s helpful when debugging logs, checking API responses, or just figuring out when something happened.

💻 For Developers: Blog Posts and Code Snippets
If you like to see how things work under the hood, I’ve also put together some guides and how-to posts. They each include practical code snippets in JavaScript and Python, as well as real-world advice for handling dates and times in your own projects.

🤔 Why I Built This (and What’s Next)
Trying to handle time for users in different countries, with holidays and unusual workweeks, can get frustrating fast. After building Pastetime for my own needs, I realized other people might find it useful too.
🔮 I’m planning to add more calculators soon, like duration calculators and tools for working hours.
