Your birth date is enough. Wooly works out the exact shape the Moon held the night you arrived — how much of it was lit, and the sign it stood in.
Unlike a birth chart, the Moon's shape barely cares about the hour: it changes by about 12° a day, so your date alone pins how full it was to within about 5 points. Give the time if you have it and Wooly will use it.
A partner, a friend, a child. Wooly puts your two Moons side by side. Their date is not stored anywhere.
The sky moves for everyone. It does not land the same way on you.
Your cosmic calendar: the favourable windows of your year, month by month, dated.
