What the lunar calendar shows
This lunar calendar lays out a whole month at a glance. For every day it gives the moon phase — from new moon through the waxing crescent and full moon to the waning crescent — along with the percentage of the disc that is lit and the zodiac sign the Moon is travelling through. Pick any month and year to see it.
It also pinpoints the exact full and new moon dates and times for the month, worked out from the angle between the Sun and the Moon. The full cycle from one new moon to the next runs about 29.5 days, which is why the phase shifts a little every day.
Phases and the moon sign
A waxing moon grows from new to full; a waning moon shrinks from full back to new. Traditionally the lunar calendar has been used as a guide for gardening, haircuts and rituals — best taken as folklore and a rhythm to follow rather than fact. The moon sign, the zodiac sign the Moon stands in, changes roughly every two and a half days and is read in astrology as a note on mood and feeling.
