Thirteen equal months
Twenty-eight days each, exactly four weeks. One day, Otium, sits outside the count.
The year opens at the equinox
Day one is the spring equinox, when light starts to outlast the dark.
Every month is a small year
Orient, Engage, Release, Integrate. Four weeks that rehearse the four seasons.
