I will have a document with Vol. 19, No. 1, January 2019 in the header.. How can I get the No. and Date to change every time I run a macro?

That is, the first doc is...

Vol. 19, No. 1, January 2019
and the next Vol. 19, No. 2, January 2019
and the next Vol. 19, No. 3, January 2019
etc...

I would like the to increment by 1 every time the macro is run and the date to change based on the current date.
