Promo countdown

An offer strip that counts down to a real date you pass.

Give it the end as a date, time and zone and it counts down with digits that flip. It is honest by design: the end is printed in words, nothing ever restarts the clock, and when the date passes the strip says the offer ended.

Build one with your agent

Build me a Taggor component like "Promo countdown" (promo-countdown): An offer strip that counts down to a real date you pass. Fetch https://taggor.dev/agent-setup/prompt.md and follow its instructions to set me up for Taggor. Ask me before you sign in, create an account, accept terms, pay for anything or type a secret. Check it with `taggor check` and publish it with `taggor publish`, and stop there. Do not promote it to production, attach it to a site, roll back anything or use --yes, --force or --force-drop-invalid unless I ask for exactly that in this conversation.
