Cut out the Sundial nearest to your Latitude. Assemble
following the instructions on the sundial sheet.
Take the Sundial outdoors, point the dial to true North and
read the shadow cast by the top of the gnomon to tell local
solar time. This is correct sun time.
To obtain clock time, you’ll need to do a little math if you
want accuracy: Subtract your west longitude from your
time zone longitude, multiply the result by 4 to get
minutes, then add the Equation of Time correction from
the chart on the next page
Example: Our Dial is located at longitude 77 West and
reads 10:05 on March 1st (day 60 of the year) . The Dial
is inDial
the
Eastern Time Zone that has a longitude of 75 W.
