Big Day
A beautiful live countdown to any date, ticking in real time.
Big Day turns any moment — a launch, a wedding, a trip, the new year — into a gorgeous live countdown that ticks down the days, hours, minutes and seconds right in your browser. Name your event, pick a date and time, and one click copies a shareable line; quick presets and your last countdown are remembered locally. Built end-to-end with AI, it runs fully offline with no login, and the entire single-file source is downloadable to self-host or remix.
