In short
The moon phase and its rise and set times matter more than most people expect near the coast. They drive how big your tides swing, and they decide how much natural light you'll have for an early start or a late finish.
Sailors and anglers watch the moon for a reason that has nothing to do with romance. Around new moon and full moon, the sun and moon line up and pull together, producing spring tides, the biggest swing between high and low. Around the half-moon points, they're pulling at angles to each other, producing neap tides, the smallest swing. Glancing at the moon phase is a quick way to guess how strong the tidal push and pull will be, without opening the tide chart at all.
Reading the calendar
Each day's tile shows the phase itself, illustrated, with rise and set times underneath. The illumination percentage tells you exactly how full the moon is that night, useful for judging how much natural light you'll actually have if you're planning a dawn or dusk session.
Why rise and set swap order
Moonrise doesn't always happen before moonset in the list, and that's not an error. Around full moon, the moon rises close to sunset; around new moon, it rises close to sunrise. Which one lands first in the day genuinely changes through the month. A small reverse-order toggle near the Sun and Moon times lets you flip the display if you find the other order easier to follow.
