MAJOR feeding periods
are 2 hours long, centered on the solunar time you see in your time table. If you have a MAJOR time of 5:30 A.M., then you would want to be at your location no later than 4:30 A.M. and remain there until at least 6:30 A.M.
MINOR feeding periods are only 1 hour long, again centered on the solunar time. That means a MINOR period of 6:15 P.M. would require you to be there no later than 5:45 P.M. and remain until 6:45 P.M.
