Day 4 overlays an equinox-anchored 364-day sacred year onto your everyday calendar — Sabbaths, appointed times, seasons, and the quiet thresholds between.
Sun, moon, and stars were set as signs for seasons and days. Day 4 takes its name — and its bearings — from that fourth day.
364 days is exactly 52 weeks — four seasons of 91 days — so the seventh day is always the Sabbath, year after year.
The year is solar and equinox-anchored. The moon is shown as an observation layer — a witness overhead, never the timekeeper.
The one or two days after day 364, before the next equinox: a threshold held in stillness, marked apart from the counted year.
