Alarm going off at 12AM every day

Same timer.... choose 1-pack or 2-pack
http://waterheatertimer.org/Woods-timers-and-manuals.html#bar

The 2-pack means you get two timers.
Both these timers can fit on one duplex outlet... so you can control two different lights from same outlet,,, and each light can have different schedule
These are lightweight lamp timers.... choose Woods 50009 for heavy duty

They also make tabletop timers

They make countdown timers that automatically go off later

Q1) Some UPM timers, and other brands, offer countdown feature in addition to regular programming.
So you choose between regular programming and countdown.
Countdown is for a bathroom fan for example.
Push the button and fan turns on for set amount of time.
After countdown is over, fan turns off automatically.

Q2) Yes all days of the week can be selected.
Set event 1 ON for all days.
Set event 1 OFF for all days.
Do not set more events unless you want more on-off events.

Q3) Switch position depends on model number.
Add a comment with model number to identify product and I will look at manual alongside you.
Or try the switch in different positions.

Review at Amazon seems to say the timer can repeat the same countdown each time button is pushed and countdown is activated.

Amazon review says:
http://www.amazon.com/General-Tools-TI150-Visually-Impaired/product-reviews/B001TOJG7Y/ref=dp_db_cm_cr_acr_txt?ie=UTF8&showViewpoints=1
The timer is easy to set. You just set the time, then hit the big "start/stop" button and the little "H" and "M" on either side of the timer display flashes.

To clear the timer, just hit both the "h" and the "m" buttons simultaneously. (so time has to be cleared)
To stop the alarm or to turn off the timer before the alarm sounds just hit the "start/stop" button.

On the back of the timer, there are 4 different on/off switches: flashing light alarm, sound alarm, vibrating alarm, and one for hours/minutes or minutes/seconds.

When I set the timer on my desk, it moved around when the alarm went off but when I turned off the vibrating function, the timer didn't move around.

If you need to turn off both the sound and vibrating alarms and use only the flashing light alarm, the light is quite noticeable by itself if placed nearby in your line of sight (within a foot or so). This would be very handy if you're near a sleeping baby! :) But if you clip it on a breast pocket, I would use both the flashing light and vibrating alarms. The vibrating alarm does make a sound, but it's not as loud as the ringing alarm.

Manuals for all UPM timers are missing key explanations, despite the lengthy manual.
I think there are 3 things to look for:
1) Program1 is ON and program2 is OFF and program3 is ON etc.
2) When setting days, be sure that ON and OFF are set for same days so there are no conflicting programs.
3) Timer gives three modes: Countdown and Random and Programming. Countdown is for a bath fan when you want to turn on fan with push of button and have timer turn off fan automatically after the countdown expires. Do not use countdown or random functions when you want timer to perform ordinary on-off functions.
