Yes, it works like a charm. On the tupility of it all.
Special thanks for the explanation too…..
Now that the code no longer produces the errors, I see that the year and month
not included in the calculation? How do I fix this?

What is likely happening is that when you read the data from the file you are
not reading a tuple, you are reading a 26 charcter string.
You have to convert that string into a tuple - the easiest way will be somthing
like this :
timet = tuple(int(x.strip()) for x in timestring[1:-1].split(','))
where timestring is the data you get from the file
The [1:-1] removes the () from the data
The .split(",") method creates a temporary list from the remaining string
breaking the string where there are commas
The x.strip() removes spaces from each item in the temporary list.
Note that the * unpack operator doesn't just unpack tuples, it works on an
iterable, so when you read the data from the file currently, and then use * on
it, it will pass 26 separate characters to the function.

Subject: RE: Subtracting dates to get hours and minutes
So far so good , I can now use a variable in datetime.datetime but it only
works if I hard-code the time/date information. Now I want to have the code
read from a file but I get: TypeError: function takes at most 9 arguments
(26 given)
I figure that the structure in the file is incorrect. What should it be? The
entry in the file is (2022, 12, 13, 5, 3, 30) but when my program tries to
use it I get the error.
The program is a bit more sophisticated now but here is the update with a
sample of the SPECIFICATIONS.txt file:

# This program compares two Timedate values, subtracts the two and

Your problem is that datetime.datetime does not accept a tuple as an
argument. It expects an integer value for the first argument, but you
supplied a tuple. In Python, you can use a sequence (e.g., tuple or
list) the way you want by prefixing it with an asterisk. This causes the
sequence of items to be treated as individual arguments. So:
Startt = datetime.datetime(2022, 12, 13, 5, 3, 30)
st1 = (2022, 12, 13, 5, 3, 30)
dts1 = datetime.datetime(*st1) # NOT datetime.datetime(st1)
dts1 == Startt # True

As is, Test A works.
Comment out Test A and uncomment Test B it fails.
In Test B, I move the data into a variable resulting with the report:
"TypeError: an integer is required (got type tuple)
