The moon's phase is the angle between the Sun and Moon as seen from Earth: 0° is the new moon (අමාවක), 180° the full moon - the poya day observed in Sri Lanka each lunar month. Between them the moon waxes through crescent, quarter and gibbous shapes, then wanes back. This calculator computes the exact phase angle and illuminated fraction with an arc-minute ephemeris, along with the moon's zodiac sign in both sidereal and tropical systems and its nakshatra - the basis of Sri Lankan nekath timing.
