Designed by Kota Nezu, the Clock parasol ” is there to block the sun, but it invites you to look for the sun.”
It is very easy to use. You have to hold the parasol horizontally to make the fabric panel end come to your eye level, and look up from the position close to the shaft. After that, adjust your position so that N of the compass points at you and S points at 12 of the parasol. And now, the vertical lines and numbers indicate hours; horizontal lines are the summer solstice, the spring/autumnal equinox and winter solstice from the top to bottom. For example, if you see the sun at the point in the figure, it means it is approximate 3:00 pm on the summer solstice.
