Debbie and Kathleen's invention answers the question: How many days ago did I open that jar of food? Their Days Ago™ Digital Day Counter counts the days from the time you open a jar. "It really eliminates the doubt of knowing when to throw [food] out," Debbie says.

The timer can be attached to a food jar using a magnet or a suction cup. Kathleen says people can use the counter to remember how many days ago they did various other things, such as watering the plants or changing the kitty litter.
