Luna is a simple and immediate lunar calendar that combines precise astronomical calculations with ancient knowledge about the effects of the Moon on Nature.

You can see the moon phases, with the exact time of the new moon and full moon, the sidereal lunar cycle, and the time of the moon's entry into the constellations and signs of the sidereal and tropical zodiac. Lunar nodes, perigee, apogee, and the ascending and descending moon cycles are also analyzed.
