From our friends at Troutlet.com…

The calendar is based upon the continental US, and as there is only a 5 minute difference between the east and west coast, one calendar can be used for both.

It has been proven that there are generally two phases of fish activity during any given day. These phases occur twice each day and are called Major and Minor. During both of these phases fish and game are more likely to be much more active.

When reading the calendar, the first time line represents the Major phase times and the second represents the Minor phase times. You should fish 30 minutes before and after each time. For example: if the time listed are 02:03am and 02:28pm, you would want to fish from 1:33am to 2:33am and 1:58pm to 2:58pm.

The days with the most active are also rated according to quality of the activity: FAIR - OK - GOOD - BETTER - BEST

Good luck!
