About

This app is meant to be simple and useful. Yes, you can Google things. Yes, you can ask AI. But this is a place where you can save your queries (just press enter  on your query of interest), come back to them, see them in a list, and copy the values you need.

I'm not charging money for this, and it will likely end up being just a small fun side project with zero outcome, but I enjoyed making it, and I hope someone finds it useful.

So if you've ever wondered how many Fridays are left until Cinco de Mayo, or what the time difference is between Jerusalem and Paris, or how much fifty dollars is in Chinese yuan, or how many minutes are left until 2050, then welcome!

Everything is written in HTML/JS/CSS, no frameworks. It's not an AI wrapper; everything is parsed and calculated here, in about ninety thousand lines of JavaScript across fifty-odd modules, with no dependencies and nothing to install.

Four of the answers draw. The day ring is a whole day as a circle, at the latitude and the season of whatever was asked about; the compass is the same sun from straight above; the clock board reads one instant in as many places as you name; and the size map lays one country's outline on another's. Each of them appears under an answer that wants it, and each has a page of its own.

Again, it's free forever. It's hosted on Cloudflare Pages and costs me about one meal per year, so I can afford that.

I built it because I actually needed it at work: we can't install anything on our computers, so a website like this makes sense. And again, I know you can Google all of it, but Google won't save it in a list for when you need to cross-check something later.

Anyway, it's useful for me, and I hope you find it useful too!

One note on privacy. Your saved queries live in your browser and never leave it. The one thing the site reports back to me is a query it failed to answer: the text of that query and nothing else. No account, no IP address, no cookie, nothing that says who typed it. That is how the calculator learns phrasings it does not know yet, so if it ever goes silent on you, the silence is already filed as homework.

City positions come from Natural Earth, and time zones from the tz database. Both are public domain, so nothing here is owed to anybody, by me or by you.
