Its main feature (and what makes it different from some of the existing countdowns for Joomla!) is that it handles browser suspend/resume events correctly. There is a wide scope of scenarios when browsers stop (pause) the scripts and timers: from putting a desktop in suspend state to switching mobile Safari tabs or even scrolling the screen on iOS devices while the module is displayed on the page. In all cases, after the browser resumes, Smart Countdown 3 calculates the time the scripts were suspended and adjusts the values of its counter automatically (no need to reload the page).

Smart Coundown 3 uses jQuery animation for digits transitions thus providing good cross-browser support.

Smart countdown includes translations for English (backend and frontend), Spanish, German, French, Italian and Russian (frontend only) and is well prepared for multilingual environments. It is aware of singular/plural forms of time unit labels it displays (Years, Months, Weeks, Days, Hours, Minutes and Seconds) for the majority of languages, including special cases – French zeros (that are singular) and Russian (third label form for values ending with 2 to 4 but not with 11 to 14), and can be extended with user-defined “plural suffices” methods for the languages that need their specific logic.

Other features:
• Years, months and weeks can be displayed in counter intervals, along with traditional days, hours, minutes and seconds
• Digits animation - virtually unlimited number of effects and styles using basic animation profiles (included) and installable profiles add-ons
• More than one countdown on the same page with individual settings
• Support for events import plugins
• AJAX used for event queries, Smart Countdown 3 will behave correctly even if its template position is cached on your site
• Various module layouts
• Responsive behavior - the module automatically scales its elements and changes its layout adapting to the template position width
• Independent font sizes for event text, counter digits and time unit labels (“Days”, “Hours”, etc.)
• RTL languages support in all counter layouts
• Custom CSS styles for all counter elements
• Option to display a "Time has arrived!" kind of message on countdown 0
• Automatic redirection (may be disabled in options) to a menu item or an URL on countdown 0 or mouse click
