Sennight — A Seven-Day Practice Experiment

DAY 1

The promise

On the first day you make one promise, and leave a question that belongs only to this week. It waits for you to come back.

DAYS 2–5

You look back

Up to twice a day, write down moments that actually happened, and choose how the effort felt: immersed, beside, or forward. Six facets, taking shape across seven days.

DAY 6

Almost harvest

The shape settles and clarifies. No countdown, only accumulation. This is not pressure. It is weight.

DAY 7

Harvest

The week becomes a stone. Everything you put in is honest in its shape.

ABOUT SENNIGHT

Sennight (晶歷) is a browser-based practice experiment. One practice lasts seven days: you make a single promise, then each day look back through mirror cards at moments that actually happened, choosing how the effort felt — immersed, beside, or forward — across six facets. After the seventh day the practice becomes a stone generated by behavioral data alone; you can keep it in the star map or let it go into the morning light. The stone chest keeps a record for every stone that can be re-read anytime; stones can also be viewed as a star map, laid along a timeline of their harvest, with adjacent stones of the same facet forming constellations. There are no login streaks, no punishment mechanics, no purchasable cosmetics; no record can be replayed; every stone is unique. Used directly in the browser.

Afterwards, memory

The stone is kept in your stone chest, a place you can return to anytime. And when the next practice begins, the stone carries an echo of the last one — and a message, left by you. You can also carry the stone with you: each one can become a card, placing that week's shape before someone else's eyes.
