Explanation:
In the center of Prague there's a clock the size of a building.
During the day, crowds gather to
watch the show when it chimes in a new hour.
The Prague Astronomical Clock's face is
impressively complex, giving not only the expected time with respect to the
Sun
(solar time),
but the time relative to the stars
(sidereal time), the times
of sunrise and sunset, the time at the equator, the phase of the Moon, and much more.
The clock
began operation in 1410,
and even though much of its inner workings have been
modernized several times,
original parts remain.
Below the clock is a
nearly-equal
sized, but static,
solar calendar.
Pictured, the Prague Astronomical Clock was photographed alone during an early morning in
2009 March.
The Prague Astronomical Clock and the
Old Town Tower
behind it are currently being renovated once again, with the
clock expected to be restarted in 2018 June.
