Just like when you see in the movie that is counting hours for a rocket launch, You can count D hours for the special moment!
Like 100 days or a whole year anniversary with your lover.
Or you can count how many hours passed from the special moment!
When the count reach to the zero, the lovely bell will ring for a minute!
Have you ever wondered how many hours it has been since you met your lover? or how many hours left to the special moment?
Easy and accurate!
