Does it have countdown function?

No, I don't think so. I've been using it for over two years and I've never come across one.

There is NO indication in the instructions that such a feature is available.

Yes, if you do not need to measure increments of less than one second. If it is set on 0 and you push start it will count upwards till you stop it.

It definitely has a count up feature and you don't need for it to count down to zero before using it. Just push the timer selection button on the right (1, 2 or 3) then press start and it will start counting up from zero. And yes, all three timers are completely independent in terms of start/stop and count up/down.

Yes, you can. Push Menu and use the middle two keys to go to System Settings. Select the Tool item. Select Power Off Settings. Use the middle two keys to set a countdown time in minutes. Works just fine on mine (Firmware 2012/03/15 1.0.23.0315)

No, it is just an MP3 player with an FM radio tuner. No clock at all the digital display is the countdown display for whatever MP3 file you are playing, or the FM radio station.

I have not discovered a countdown timer, which is not to say there is not one with certainty. There is much to discover through use, not all that well documented in the manual or online.

I just tried to set it for a 24 hour countdown. The most I could do was 9:99:99. I don't know about a count up, but I imagine it would be similar.

Press the "M" and "S" simultaneously to zero out the time. Then hit the "start" button to count up. Not intuitive! :)

Yes. Don't forget that it has "funtions." It is a clock also. So you have to push the "timer" button for timing, and when done, push the "clock" button, and vice versa. It's THE best timer I've ever had. Other than the weird way it hangs (vertically, since the magnet is on one side), I couldn't think of anything else I'd want in a timer.

Yes, there is a calculator feature. It also has a stopwatch and a calendar. All in the Tools section

No. The highest number, no matter what you are using it for, is 9 hours and 99.99 seconds. I actually have two of these so I have the ability to time two things at the same time. It is the best timer/clock/counter I have ever owned and I have owned many as I am an avid cook. I also use it for timing other chores such as watering the lawn, laundry, etc. My memory isn't what it used to be! With magnetic back it hangs easily on my refrigerator and also is small enough that I can carry it in my pocket.

No...this one does NOT have a timer that ticks...only a round plastic button that you turn to the right, and it works itself to the left, then off. No ticking.

It can count down from any time you set to. It will definitely count down from 35 seconds.

Tried setting countdown to 24:00:00 and it only went as far as 2:40:00 - so no, it will not count down 24 hours. Sorry, I did not try counting up 24 hours.
