Share the link in Slack, email or an invite, whoever opens it sees the time in their zone. The link carries the event only; nothing is stored.
Create or edit the event
How it works
Fill in the title, date and the time in the zone you're thinking in, then add the zones your attendees are in. The card at the top shows the event in your zone with a live countdown; the shareable link carries the whole event in the URL. When a colleague opens that link, the card re-localises to their detected zone automatically, so nobody has to do the mental arithmetic, and nobody joins an hour early.
Everyone can add it straight to their calendar: the .ics download and the Google/Outlook links all encode a single absolute instant, so the event lands at the right moment in every calendar regardless of the recipient's zone. It's all computed in your browser from its built-in time-zone database: it works offline, and the event you type is never sent to a server or stored anywhere.
Frequently asked questions
How is this different from just typing the time in an email?
A typed time ("3pm ET") makes every recipient convert it themselves, and someone always gets it wrong, especially across a daylight-saving change. This link shows each person the time in their own zone and drops the exact instant into their calendar, so there's nothing to convert and nothing to get wrong.
Does the recipient need an account or app?
No. They open the link in any browser and immediately see the event in their zone. Nothing to install, no sign-up, no tracking.
Is the event stored on your servers?
No. The entire event lives in the link's URL fragment, which browsers never send to a server. We store nothing: if you don't share the link, the event exists only on your screen.
Will it land at the right time in everyone's calendar?
Yes. The calendar files use one absolute UTC instant, so Google, Outlook and Apple Calendar all place the event at the correct local moment for each attendee automatically.
Should I put attendee names in it?
Only if you're comfortable with them being in the shared link. The card shows zones, not people, by design, keep sensitive names out of a link you post in a shared channel.
