Claus Tøndering


Hi, my name is Claus Tøndering. I live in Kongens Lyngby, Denmark.

I was born in 1953. I'm a computer engineer by profession, having a Master's degree from the Technical University of Denmark. I retired in January 2020.

My home page is here. There, you'll also find two documents I've written, namely, Frequently Asked Questions about Calendars and an introduction to surreal numbers.

My Wikipedia user name, oz1cz, is actually my amateur radio callsign. I am, however, not currently active as a radio amateur.

In case you're wondering: The ø in my name is a special Danish letter. It is pronounced more or less like the i in the English word sir.
