A small tool for time zone conversion

I’m writing this short blog post to let you know about a small (unassuming) tool I've just written, to help you visualize suitable times for events involving multiple time zones.
You can download it at:
It was loosely inspired by tools such as World Time Buddy:
Except, it’s more basic, and a lot uglier.
If it looks like a UI designed by a backend developer, that’s because it is 😁
What’s the point, then?
There are multiple advantages:
- There’s a dark theme,
- There are no trackers,
- It’s Open Source,
- And more importantly, it works offline.
Just save the HTML file to your computer and open it in a Web browser.
OFFLFIRSOCH
Say what?
OFFLFIRSOCH. It’s apparently pronounced “awful fur sock”.
It’s an idea from Solderpunk – the creator of the Gemini protocol – and it means “OFFLine-FIRst SOftware CHallenge”.
The spirit of OFFLFIRSOCH, in short, is […] to identify something which you yourself actually do online at least semi-regularly which you know full well could be done offline, and to make that happen.
That’s how I got the idea of developing this small utility.
Indeed, why send requests to a server when time zone conversions can be done entirely locally on your computer?
I found out about this “challenge” on March 29, and it ends on March 31 😅
Now, to be honest, I doubt my tool qualifies for the challenge, as it’s… a Web page! So much for “offline FIRST”.
I mean, it can definitely work 100% offline, but if anyone ever finds it useful, they’ll be tempted to host it on a server, which defeats the purpose of the entire thing.
