How Many Moon Phases Are There?

There are 9 Full Moon Phases in Total

The moon in Persona 3 Reload follows the phases of the moon in real life, with 9 phases in total. Each phase lasts for approximately 2-4 days unless an anomaly within the Dark Hour ensues. Players can ascertain the next moon phase by looking at their calendar.

Since the moon, sun, and planets move constantly, each moon phase comes with a variation. For instance, a crescent may be a bit larger or smaller than yesterday, but it is still considered a crescent.

Focus on Full Moons

Full Moons have a significant impact in Persona 3 Reload's story, for it is during Full Moons that powerful boss Shadows appear outside of Tartarus. Find and eliminate these Shadows to unlock more areas in Tartarus and enable further exploration.

Full Moons act as due dates, which means you need to explore Tartarus until you get to the locked gate and do as much as you can regarding your Social Links, Quests, and Social Stats before a Full Moon arrives.

Fusion Accidents are More Frequent During New Moons

Fusion Accidents are strange occurrences in the Velvet Room wherein the resulting Persona of a Fusion is different from the one originally intended.

These occurrences happen more often during New Moons, so keep an eye out for them if you wish to take advantage of Fusion Accidents!
