Since Madeira uses GMT but is 16 degrees west of Greenwich,his suntime of birth is 09.16( 16 degrees are 64 minutes)
JR, you are partially correct, however:
1) To be more accurate, the longitude of Madeira, Portugal is 16.9595 degrees. So please adjust by
68 minutes.
2) You also need to adjust for the Equation of Time. The adjustment is also given by bazi-calculator.com, which is
14 minutes.
To avoid the headache, one can just enter Madeira and birth timing into bazi-calculator.com made by
@Voytek to get the result of 8:58 am --> Geng Chen hour.
Tell me, JR, is he really seen as a cult figure in his city of birth?
Note: some people disregard the use of Equation of Time, although they adjust for DST and longitude. But this case study is
one evidence that Equation of Time should be taken into account.
