“What time is it?” Prague’s Orloj: “Before I answer, how much do you know about astronomy, and which definition of ‘day’ are we using?” #Orloj #Prague

An hour isn’t always 60 minutes. Prague’s Orloj divides daylight into 12 “unequal hours”: longer in summer, shorter in winter. There’s something lovely about a clock that measures your place in the day, rather than just how late you are. #Orloj #Prague

Most clocks answer one question: what time is it? Prague’s Orloj puts the Sun, Moon and sky into the picture. Explore an interactive astronomical clock: worldastronomicalclock.com

Ever stood in front of Prague’s Orloj and wondered what all those rings mean? I built World Astronomical Clock to explore it in motion. Speed up time, change location, and watch the Sun, Moon and rings move. worldastronomicalclock.com #Prague #Orloj
