I Built a Simple Tool to Check Other Time Zones — Let Me Tell You Why

I've always found it weirdly frustrating to check time zones.

Every time I needed to know what time it was in another country — say, for a call, a game release, or even just curiosity — I’d end up on some slow website with way too many ads, popups, and a dropdown that somehow never had the city I wanted. And sure, you can "just Google it", but even that gets messy when you're checking multiple cities or comparing against your own time.

So I built something for myself.

It’s called World Time Checker — a simple, clean React + Vite tool where you can just type in a city or country, and it tells you the current time there, your own time zone, and the time difference between the two. No distractions. No frills. Just the info I actually want.

What surprised me the most was how quickly it came together. React + Vite made the whole process smooth, and once I figured out how to handle time zones and fetch accurate data, everything just clicked.

I didn’t build it to show off. I built it because I needed it (is this OCD?). And now, it’s one less tab I have to open when planning my day across time zones.

If you've ever had that same frustration, this tool might be exactly what you didn't know you needed.
