// This formula finds the number of missed increments necessary to make the rise hour a 24-day loop.
// The offset increases on the first day of the loop and is multiplied by the number of completed loops.
float incrementOffset = (24.0f - (24.0f / mDailyIncrement)) * std::floor((gameDay + startDay) / 24.0f);

// This odd formula arises from the fact that on 16 Last Seed, 17 increments have occurred, meaning
// that upon starting a new game, it must only calculate the moon phase as far back as 1 Last Seed.
