Stop Struggling With Timezones: Free Tools and Real-World Tips for Developers

#productivity #webdev #beginners #showdev

Have you ever spent hours wrestling with date math or trying to figure out why a meeting time, deadline, or log entry just didn’t add up? I kept running into this pain, so I built Pastetime.com/ as the set of tools I wish I’d had all along.

If you’ve ever wondered:

How many business days are between two dates (including weird weekends and local holidays)
How to convert between UTC and your local time (or another city)
How to quickly translate between ISO, Unix, and RFC 2822 timestamps

You’re in the right place.

Let me show you how I made date and time math painless (and how you can too).

🚀 Free Tools I Built at Pastetime.com/

🗓️ Business Days Calculator

Enter two dates, pick your weekend days, and add any holidays—get an instant answer. No more spreadsheet formulas or mistakes on deadlines.

👉 Try the Business Days Calculator

🌐 UTC to Local Time Converter

Paste in any timestamp (ISO, Unix, or RFC 2822), and see what time that actually is for you, or any city you need. Perfect for debugging logs, API calls, or planning global meetings.

💻 For Developers: Real Code, Real Problems

I’m a dev myself, so I know most of us want to see how stuff works. I’ve written a few detailed blog posts that walk through the logic, show you code snippets in JavaScript and Python, and share lessons learned from real-world headaches.

Check them out:

🧩 Why I Built This

I was tired of:

Remembering which days count as weekends in different countries
Getting tripped up by daylight saving time
Hardcoding holiday lists (and still missing a local one)
Struggling to convert timestamps in logs

So I put it all in one place. No logins, no ads, just fast, focused tools.

💡 Let’s Learn Together

If you have a weird time zone story, a nasty bug you finally squashed, or a request for another tool, I’d love to hear it!
