Days 1 and 3, where the Sun, Earth, and Moon are aligned, represent the new moon phase, which typically correlates with higher tides and increased fish activity near the shore. Therefore, these two days are likely when John will get the best catch while fishing.
Looking at the lunar phases and the Sun-Earth-Moon alignments:
Day 1: The Sun, Earth, and Moon are aligned in a straight line, indicating a new moon phase. This alignment typically results in higher tides, which could lead to better fishing.
Day 3: Similarly, the Sun, Earth, and Moon are aligned in a straight line, suggesting another new moon phase. Like Day 1, this alignment could also bring higher tides and potentially good fishing conditions.
The alignment of the Sun, Earth, and Moon influences the tides, and the highest tides often occur during the full moon and new moon phases when the Sun, Earth, and Moon are in a straight line.
