This is a simple html countdown timer that counts down Mondays, Days, Hours, etc to a date/time defined in a variable in your BrightAuthor project. The attached project example uses BrightAuthor 4.7, but you can use the same timer with any brightauthor version that supports html content.
You can edit the html to change colors or remove months, days, etc.
