Major Snow 大雪
Deep winter. The shortest days are ahead.
Dàxuě · begins 7 December 2026 · approximately fifteen days
The darkest fifteen days of the year in the north. Energy is genuinely lower — measurably so, and for reasons that have nothing to do with willpower. The right response is a smaller, warmer, more repeatable week.
The three micro-seasons
Every term divides into three pentads of about five days.
- Birds stop calling
- Tigers begin to mate
- Reeds sprout
What to do in these fifteen days
- Shrink your expectations for the next two weeks by a third. Plan it rather than discovering it.
- Keep one warm, well-lit room as your default. Light a real lamp, not a screen.
- Cook once, eat three times. Decision fatigue peaks in the dark.

One question
What would you do differently this week if you assumed your energy was genuinely lower?
