The most advanced countdown in the world Tempus is a countdown built as a plugin for jQuery and the visual part of it is made with Raphael js, which supports animations even in old browsers, not to mention that the visual part is displayed as SVG, maintaining the visual crispness on any size and any display. Multiple Time Events Tired of changing your time event over and over after the countdown finished? With Tempus you can add how many start/end dates you need in the form of a list with its own complete and active callbacks, so you can sit and relax that Tempus will do its job. Responsive Tempus is all about making this countdown responsive and working even on old mobile devices. If the browser can support SVG, it will work. Design API The way Tempus was made, allows you to make any type of design you could wish for. It`s as simple as just adding your own custom made images in the form of an object and your countdown will take life, with custom fonts and sizes.
