How to read the clock

Count the value of all the illuminated lamps together, the values being:

- 1st row - each lamp counts 5 hours

- 2nd row - each lamp counts 1 hour

- 3rd row - each lamp counts 5 minutes (every 3rd lamp is red to signal 15minutes)

- 4th row - each lamp counts 1 minute

The Mengenlehreuhr (German for "Set Theory Clock") or Berlin-Uhr ("Berlin Clock") is the first public clock in the world that tells the time by means of illuminated, coloured fields, for which it entered the Guinness Book of Records upon its installation in 17 June 1975. Commissioned by the Senate of Berlin and designed by Dieter Binninger, the original full-sized Mengenlehreuhr was originally located at the Kurfürstendamm on the corner with Uhlandstraße. After the Senate decommissioned it in 1995, the clock was relocated to a site in Budapester Straße in front of Europa-Center, where it stands today.
