ok - it might be a bit different, because I also incorporate the maori fishing calendar in my calculations for the day ratings.
When you look at the fishing calendar - look out for those days with fishing times shown in bold. That indicates they are just after sunrise or before sunset at your location.
The combined effects of sun and moon at those times increases the feeding activity.
These are good days and times to look out for besides the general day rating.

If people concentrated on the really important things in life, there'd be a shortage of fishing poles.
