The moon and the count of days — a lunar & Anāhuac cultural calendar by Project POCA.
A free calendar feed with every new moon, first quarter, full moon, last quarter, equinox, and solstice — computed by the same model that powers the Metztli app. Subscribe once and it stays current in any calendar app that supports ICS.
Moon phases, the tonalpōhualli and xiuhpōhualli counts, your own calendars and ICS subscriptions — together in one app. Coming to Google Play.
