About
the calendar on your wall was made in rome. its months stopped following the moon long ago, and its new year falls on a day the sky doesn't mark.
moonth keeps the older count: thirteen moons of 28 days, four weeks each, starting at the spring equinox where you live. each morning it tells you what day it really is and what the moon is doing, and gives you one thing to grow and one to let go.
today
the day of the moon you are in, tonight's real phase, and the seven lights the days are named for. the four turnings of the sun arrive as they come, with the four fire days between them.
what the moon asks of you
one thing to grow and one to let go, with the reason underneath. keep it and a plate lights on your shell, the turtle that carries the year.
your true sign
the horoscope still uses the sky as it was mapped over 2,000 years ago. moonth reads where the sun really stood among the stars at the minute you were born, and for nearly 9 in 10 people that is a different sign.
your people
add someone you love and see their true sign and what to grow with them today. no birth time needed.
the body's moon
if your body keeps a monthly cycle, moonth can walk it beside the moon, with its own rites.
a letter from the sky
a short note each morning at 8:00, or the evening before. or none at all.
share the day
story-sized cards drawn from the real sky, ready for your stories.
learn
twelve short chapters on where the calendar came from and why the stars moved. and twenty ways to draw the moon, from ink to stained glass.
on your phone only
there is no account and no server. what you enter stays on your phone, and moonth works offline.
moonth+ is open to everyone for now. there is nothing to buy in the app.
moonth is for reflection. it does not give medical advice, and the body's moon is not a contraceptive or a fertility tool.

What's New in moonth
1.0.1
November 10, 2026
weeks now run monday to sunday, so every moon reads like a calendar. the body's moon says plainly that its forecast is an estimate, never medical advice. privacy, support and terms are a tap away in settings. a clearer welcome, a share card that fits your stories, and many small fixes.
