Purnima (Full Moon) is when the Moon is fully illuminated - a time of culmination, high energy and spiritual practices. Many festivals and fasts fall on Purnima.
Amavasya (New Moon) is when the Moon is not visible - a time for new beginnings, ancestor worship (Shraddha) and inner reflection. The lunar cycle from one new moon to the next takes about 29.5 days, and each tithi (lunar day) has its own significance in Vedic tradition.
