What major and minor periods mean
In common solunar table conventions, major periods are associated with the moon passing overhead or underfoot; minor periods are associated with moonrise or moonset. The labels describe the table’s timing model. They do not measure feeding at your fishing spot.
Publishers may display different window lengths or a central time rather than a start and end. Read the convention used by the table in front of you. Do not assume a rule from one provider applies to every app.
Check location, date and the displayed time
A useful window needs the correct place and date. If you are traveling, verify how the app or table presents time before you schedule the outing. Time zone and daylight saving conventions can explain apparent disagreements between tables.
A period can cross midnight. A window shown as 23:30–01:30 continues into the next calendar day; it does not end earlier that evening. Check the relevant date as well as the clock time when comparing it with travel or access hours.
Use a window inside a larger plan
- Check conditions first. Review the official forecast and any warnings for the location.
- Choose a practical session. Work within daylight, access, travel and your available time.
- Compare the overlap. See whether a major or minor period overlaps that session.
- Recheck before departure. A lunar timetable does not account for every weather change or local constraint.
Suppose a major period is shown as 5:50–7:50 a.m., but you cannot reach the water until 8:30. It is useful context, not a reason to rush or assume the rest of the morning is pointless. Plan around the hours you can safely use and what you know about the spot. These times are illustrative.
Where this fits in Fishing Barometer
The Best Times (Solunar) section displays major and minor periods. Read those windows alongside the score breakdown, weather and pressure trend. The screenshot shows example app data, not today’s times for your location.
The app’s conditions score combines several factors. A high score and a major period are not two independent confirmations that you will catch fish. They are parts of a planning aid with overlapping inputs.
For a complete sequence from choosing a location to checking your departure plan, use the fishing forecast guide.
Common questions
Are solunar periods guaranteed feeding times?
No. They are suggested periods from a timing model. Weather, location, species and conditions at the water still matter.
Why do two solunar tables show different times?
Check the selected location, date, time zone, daylight saving setting and whether the display shows a center time or a full window. Providers may also use different calculation and presentation conventions.
Sources & context
Weather references support the planning and weather context. Solunar publishers describe their own table conventions, not proof of a catch guarantee.
