Analemmatic Sundial - Telling time at Terry Hershey Park: A special kind of clock


An analemmatic Sundial in Texas - What does it look like?

4:30 PM in March
Your own shadow indicates the time on this special sundial Of course, the sun knows nothing
about daylight savings time, so there is no adjustment for that on this special clock, which also has its own name:
Analemmatic Sundial 

Analemmatic Sundial explained on plaque next to the sundial at Memorial-area park.
You basically have to position yourself on the right spot for the month and day of the month,
to cast the right kind of shadow. The marked spots adjust for the varying  angle of the sun's daily trajectory
over the course of the year.

The sundial does not work with moon light, or artificial light from a lamp post
- at least it does not work correctly

Location of sundial on the West Houston Map: The sundial is installed on a little hill near the Gazebo
North of  the enclosed playground.
Memorial Drive, South of I-10, near Langham Creek
