Count down the days, hours, minutes, and seconds to the celebration! The Birthday Countdown Clock stands 3” x 5” tall, and comes with a long-lasting lithium battery. Once you have reached the big day, the clock can be set to display the current date and time, or you can start counting to next year’s birthday! Counts down from any date from the year 2049 down! Can be re-set over and over for years of enjoyment.
