The first day of the week is Friday. Each month is an even 28 days, which is noted by the number at the top of each day. The number at the bottom is the traditional calendar date. The moon quarters are every 7-9 days and denoted by a symbol that reflects the quarter. Each of the celestial holidays are also noted with a symbol of a star/sun. This is a slow calendar and a bit of a trickster since most of us are on autopilot with the calendar we engage.
