FAQ
Is the embeddable countdown truly self-contained?
Yes. The exported HTML/CSS/JS snippet has zero external dependencies — no CDN, no tracking, no API calls. It runs entirely in your visitor's browser using setInterval. You can paste it into any plain HTML page, a CMS post, or an email-friendly stub. The ICS calendar export is a separate .ics file that opens in any calendar app.
How does timezone handling work for visitors?
Two modes: 'visitor-local' uses each visitor's own browser timezone (so everyone sees the countdown relative to their local clock — correct across DST), or 'fixed timezone' locks the target to a specific IANA zone (e.g. America/New_York, Europe/London). Internally the target is stored as a UTC instant and rendered with Intl.DateTimeFormat, so DST transitions are handled automatically.
What happens when the countdown reaches zero?
Three on-finish behaviors: show a custom message (default), hide the widget entirely, or redirect to a URL. After the target, an optional 'count-up' mode shows elapsed time since the target — useful for tracking how long since a launch or event.
Can the countdown recur annually (e.g., a birthday)?
Yes. Toggle 'Recurring annual' and the tool computes the next upcoming anniversary of the target date/time. When the current year's anniversary passes, the live widget automatically rolls forward to next year's occurrence.
