Q: Will this work inside Notion, Ghost, WordPress or a static site generator?

Anywhere a plain <iframe> is allowed, yes. Notion and similar tools that ask for a URL rather than HTML will accept the src on its own — copy just the URL from the snippet. Platforms that strip iframes entirely, which includes most hosted comment systems and some locked-down CMS editors, will not work, and there is no version of this that gets around that.

Question 1

Is this really free, and will it stay free?

Accepted Answer

It is free, and there is no account, no key and no rate limit. It stays free because it costs us almost nothing: the files are static, they are served from the same host as the rest of the site, and they make no requests back to us once loaded. If that ever changed we would leave the existing files where they are rather than break pages that already embed them.

Question 2

Can I use a city that is not in your list of five hundred?

Accepted Answer

Yes. The city name in the clock is just a label, and the zone is any IANA identifier, so ?tz=Africa/Kampala&city=Kampala&flag=%F0%9F%87%BA%F0%9F%87%AC works even though Kampala is not one of our five hundred. The only thing you lose is the link back to a city page, since there is not one — leave slug off and the credit points at the homepage instead.

Question 3

Why does the converter say we are outside working hours when we are not?

Accepted Answer

It uses a fixed nine-to-six window at both ends, which is a simplification and will be wrong for anyone on a different schedule. It is meant as a glanceable signal, not a scheduling authority. If overlap matters to your decision rather than your afternoon, the overlap analysis is the more careful treatment.

Question 4

Does the countdown work for a date in the past?

Accepted Answer

It replaces the digits with a short completion message and stops the timer, so a page with a stale countdown degrades quietly rather than showing negative numbers.

Question 5

Will this work inside Notion, Ghost, WordPress or a static site generator?

Accepted Answer

Anywhere a plain

</code> is allowed, yes. Notion and similar tools that ask for a URL rather than HTML will accept the <code>src</code> on its own — copy just the URL from the snippet. Platforms that strip iframes entirely, which includes most hosted comment systems and some locked-down CMS editors, will not work, and there is no version of this that gets around that.
