1) Clicking any clock and going to the equinox page, you then click on
the equinox (5:05 EDT for my case - Ottawa)

3) The time difference to noon is 2h 57m 31s
Multiply x 15 - you get 44d 22m 45s E

Multiply by 15 gives 41d 52m 45s E
Open a new clock and enter the longitude, and equator
The result is near a town called Chisimayu in
