# 1. How to read the time The flashing yellow circle indicates the seconds, where bright yellow represents even and dark yellow represents odd numbers. The first row from the top consists of 4 red fillets, each of which represents 5 hours. Multiply 5 by the number of lit fillets ( = H5) The second row from the top consists of 4 more red fillets, each of which represents 1 hour. Add the number of lit fillets to H5 from above. This is the number of hours (in 24h system). The second row from the bottom consists of 11 red and yellow fillets, each of which represents 5 minutes. Red fillets mark 15 minute intervals. Multiply 5 by the number of lit fillets, irrespective of red or yellow ( = M5) The bottom row consists of 4 red fillets, each of which represents 1 minutes. Add the number of lit fillets to M5 from above. This is the number of minutes.

The original full-sized Set Theory Clock (Mengenlehre Uhr) is located at the Europa Center (Wittenbergplatz), Berlin, Germany. Figure 1.1
