Thanks for the response.
I must have spent hours looking on-line for a method to treat datetime
variables yet not one site mentioned the "pickle" module you indicatged. I
did, however solve my problem. It may be a kluge but it seems to work.
I learned that I cannot use print() to display the value of datetime but
once I saved it to a file, I could see it. If I used "d3 = d2.isoformat" it
could be sent to a file with a write statement. Apparently, it gives a
write/read format and places a T between the date and time as a separator.
In trying to read it back into the program and work the calculation, I had
to replace the T with a space and some formatting. It all worked.

Given:
import datetime
To convert a datetime d to an ISO-format string, you can use:
s = d.isoformat()
To convert an ISO-format string s to a datetime, you can use:
d = datetime.datetime.fromisoformat()
