I wanted one page that answers "how long until X" for anything: the next F1 race, tonight's anime episode, Nowruz, the next Falcon 9 launch. No single API covers all of that, so CountdownBoxes pulls 3000+ upcoming events from 38 sync jobs into one model. Every category is also a webcal/ICS feed your calendar refreshes forever, any event embeds as a live widget in one iframe, and one tap sets a push reminder. You never need an account.
