Problem #1. On model #DT300 the instructions under Set Time of Day # 3 does not change the day. The only place I can get the day/s to change is under the programming. What is wrong with it. I have cleared it many times but still cannot figure it out. Problem #2. Under Set/On/Off Times line 3 if I want to start on a specifice day, i.e., Wed and then repeat it for a week under the programming do I sratrt with the day as Wed? If I do that it will not know that I want to keep the same setting for a week. I will be gone a week. How do I set the days? thank you.

I do not see a week button either, and sure enough the Intermatic manual says press the WEEK button to revise ON OFF times. The GE manual says exact same thing. And so does the Woods manual.
I think what the instruction means is this:
To revise programs, press Progam button as many times as needed to arrive at the program you want to change. For example program1 ON or program1 OFF etc.
Then reset the program as shown in step 5 using the Hour button to set Hour, and Minute button to set minutes, and day button to select the days or blocks of days (including all 'week' as one of the choices).

Both timers will not operate?
I test timers and a percentage arrive defective. There is no repair for defect timer. This timer has 1 year warranty.
There is no load rating on this timer, at Intermatic, GE or Woods. Timer is older style and probably rated for 500-800Watts incandescent light bulbs only.
Also test outlet with circuit analyzer to make sure polarity is not issue. This is a polarized timer, and outlet wiring must be correct for electronic timers.
Make sure each program has ON and OFF time. So set program1 ON, and then set program1 OFF. And make sure same days or blocks of days are selected for each.
When setting on and off times, make sure there are no overlaps or conflicts that cause timer not to function correctly.
Another thing is setting timer for 12:00 midnight. It's better to select 11:59pm so the day is clearly understandable to timer.
When reading complex manuals, I write out the steps until things are clear.

Intermatic DT300 is same timer as Woods 59203 and GE 15091

To set days, look at #5 ... go down to step 3 where it says 'press the DAYS button to choose the day or groups of days..."

Hi

Programming:
Set present time
Then set ON time for program 1
Set OFF time for program 1
Then set ON time for program 2
Set OFF time for program 2
Most timers will not function if there is a conflict in programming > for example Program 1 says ON at 6 and OFF at 7 and Program 2 says opposite or has overlapping times
When events are set, press SET once > this will put timer in RUN mode

If manual override works, and you set programming correctly, but timer does not carry out instructions, I guess the timer is no good.

Intermatic has 24 hour timers with 2 on-off per day
http://www.intermatic.com/products/timers/consumer%20indoor%20timers/lamp%20%20appliance%20timers.aspx
Intermatic has 7-day digital timers (all digital timers today are 7 day where you select the day that each program works)

Thanks.

You need to program the timer so it turns on-off at specified times.

But first we need to identify your timer for sure.
Have a look at link below.
http://waterheatertimer.org/Woods-timers-and-manuals.html#59203
If your timer does not show, then add a comment with description of timer.
I have extensive files on timers.

Intermatic DT300, GE 15091, and Woods 59203 are the same timer.

Here are instructions for Woods 59203:
Plug timer in until battery is recharged.
If display will not show, then timer battery needs to be plugged into outlet for 1 hour until internal battery is recharged, or timer is bad, or electric circuit is tripped off, or electric circuit heeds to be tested with circuit analyzer.

Once display shows, then unplug timer for programming.
Set current time:
Press and hold CLOCK button.
Press HOUR and MINUTE to set correct time with am and pm.
Press Day button to set current day.
Release clock button.

Program timer:
Press PROGRAM button until "1 ON" displays. This is program1 ON.
Press MINUTE and HOUR buttons to set ON time for program1
Press DAY button to choose day or group of days for program1 ON

Press PROGRAM button until "1 OFF" displays. This is program1 OFF
Press MINUTE and HOUR buttons to set OFF time for program1
Press DAY button to choose day or group of days for program1 OFF

Press PROGRAM button until "2 ON" displays. This is program2 ON.
Repeat steps above to set ON and OFF time for 5 programs.

When programming is completed, press CLOCK button to exit programming.
Press ON/AUTO/OFF button until Auto displays.

Make sure lamp is turned on.
Make sure bulb is good.

If instructions don't fit your timer, then add a comment with model number or full description and I'll post those instructions.
Also you can take advantage of Fixya phone service where expert speaks with you over the phone for a price.

mcdevito75 here, The stem on your westclox has 2 positions, First pull the stem out to set the time of day, keep cycleing the watch until you come to 1 day before the day you want. NOW! push the stem back in. NOW! slip a finger nail just under the crown and gently, gently kift the crown to it"s first position, it may take a little practice so be patient, once in it's first position you can change the DATE easily, change the DATE to 1 DATE before the DA you want, push the syem back in and pull the stem back out and set the day/date and time of day. Your watch is set and will change on time a little past mid nite.
