I was wondering what year Did The Munsters Today End.

It began in '88. Was renewed for second season in '89. Either '89 or '90 as there was no third season.

Think the last episode was around May 1991

there were actually three seasons of the show from 1988 til 1991. It was still being aired here in the UK as late as 1996. The show may also be getting re-aired soon (hopefully).
