Several years ago Hudson's Bargain Center had a countdown clock for sale, a big digital read-out clock that counted down the days, hours, minutes, and seconds. I knew it would come in handy and bought one. I've used it several times for big events and deadlines, and I've loaned it to friends for their big day countdowns: things like retirement, graduation, weddings, etc.
In between uses I set it for a countdown a few years from now and let it run in my house. It has medium bright red digital numbers so it makes a good night light. Well, that and it makes a good conversation piece.
"Oh, that's my countdown clock."
"What's it counting down?"
"But it's got 708 days, 14 hours, 32 minutes and 29 seconds on it..."
"Yes, it does."
"What happens in 708 days and 14 hours?"
"We'll just have to wait and see."
I'm thinking of resetting it for 345 days, 11 hours, 6 minutes and nine seconds. That means the countdown will end sooner. We won't have to wait as long to see what happens.
