Thanks for your note. On your points...

(1) I wasn't aware that there were errors in the serial date function.
Thanks for drawing that to my attention.

Sorry, it appears I was not clear here. I am not saying there are errors in
the serial date function, just that it is much easier to make a mistake in
giving a serial date rather than the date date. For example, you said the
serial date for Dec 1st 1979 is 29220. I believe you will find that it is
actually 29190, you gave the serial date for 30th Dec 1979, making exactly
the mistake that I believe is so easy to make :-). Not seeing it as a date
makes this all to easy.

Regards

Bob
