Event time announcer
Set a time in one place and share the link. Everyone who opens it reads the time on their own clock, and the page says which zone it was anchored to.

The instant is anchored to 18:00 in UTC (UTC+00:00), and shown above in UTC, which is the same clock. Anchoring to a place rather than to a fixed offset is what keeps it right through a daylight saving change.

"We go live at 6pm" is not a time. It is a time and a place, and the place is usually missing. The reader then guesses, converts wrong, or asks. Sharing one link removes the guess: whoever opens it sees the moment on their own clock, and the page states the zone the instant was anchored to so it can be checked rather than trusted.
The instant is anchored to a named place rather than to a fixed offset, which is the part most tools get wrong. "18:00 in London" survives a daylight saving change. "18:00 UTC+1" does not, and quietly becomes the wrong hour for half the year.
What the link contains
Everything, and nothing else. The date, the time, the zone and the event name are all in the path, so the link is readable before it is clicked, works forever, and needs no database on our side. Nothing about the person who opens it reaches us.
It is also deliberately plain text. A link that survives being pasted into a forum, a chat client, a release note and a support page has to avoid anything a Markdown parser or a chat client will mangle, which rules out the encoded blobs most share links use.
A note on how it is served
Every announcement is rendered by one static page that reads the instant out of its own address. That keeps the site static and fast, and it means an announcement can never break or expire. The trade-off is that a search engine sees the same page for every announcement, so individual ones are not indexed separately. That is the right trade for a link you share rather than a page you rank.
