closing and storing (閉藏 bì cáng). Go to bed early and rise late — wait for the sunlight. Leave the cold, stay near warmth, and do not let the skin sweat open.

This is the response to winter qi — the way of nourishing the storing (養藏). Going against it is said to injure the kidney, so that spring brings weakness and collapse and there is less to carry the bringing-forth.

• This fortnight's advice was written for a place averaging 34.0°F at this point in the year. At MSP Intl, MN the 1991–2020 average is 16.1°F — cooler by 17.9°F.
• 'Major Cold' is a phenological marker from the Yellow River valley — what observers saw, not a temperature threshold. The nearest thing your own record has to it: at MSP Intl, MN the last freeze of spring does not clear until April 25, still 95 days off. This fortnight typically carries about 14.6 days at or below freezing.

If Yang deficiency came out high for you. Traditional theory associates Yang deficiency with feeling the cold sooner than the people around you. That is a theoretical association drawn from the classical literature, not a research finding. Your average low this fortnight is 8.4°F, and about 14.6 days typically fall to freezing or below. Whether any of it matters for you is something to observe, not something this page can tell you.

Pentads: 雁北乡 · 鹊始巢 · 雉雊

Same seasonal passage as above — the classical text gives one instruction per season, not one per fortnight.

• This fortnight's advice was written for a place averaging 33.1°F at this point in the year. At MSP Intl, MN the 1991–2020 average is 16.1°F — cooler by 17.0°F.
• 'Minor Cold' is a phenological marker from the Yellow River valley — what observers saw, not a temperature threshold. The nearest thing your own record has to it: at MSP Intl, MN the last freeze of spring does not clear until April 25, still 110 days off. This fortnight typically carries about 14.8 days at or below freezing.

If Yin deficiency came out high for you. Traditional theory associates Yin deficiency with internal dryness and a sense of heat from within. That is a theoretical association drawn from the classical literature, not a research finding. Your average high this fortnight is 23.4°F, and 31.1% of days typically see measurable rain. Whether any of it matters for you is something to observe, not something this page can tell you.

Pentads: 鹖鴠不鸣 · 虎始交 · 荔挺出

Same seasonal passage as above — the classical text gives one instruction per season, not one per fortnight.

• This fortnight's advice was written for a place averaging 36.3°F at this point in the year. At MSP Intl, MN the 1991–2020 average is 22.4°F — cooler by 13.9°F.
• 'Major Snow' is a phenological marker from the Yellow River valley — what observers saw, not a temperature threshold. The nearest thing your own record has to it: at MSP Intl, MN the first freeze of autumn has arrived by October 10 in half of years — 58 days before this fortnight begins. This fortnight typically carries about 14.4 days at or below freezing.

If Qi stagnation came out high for you. Traditional theory associates Qi stagnation with mood that moves with the season; the classical texts tie autumn's gathering-in to it in particular. That is a theoretical association drawn from the classical literature, not a research finding. Daylight at your latitude is 8h 54m, down 22 minutes from two weeks ago. Whether any of it matters for you is something to observe, not something this page can tell you.

Pentads: 虹藏不见 · 天气上升地气下降 · 闭塞而成冬

Same seasonal passage as above — the classical text gives one instruction per season, not one per fortnight.

• This fortnight's advice was written for a place averaging 40.6°F at this point in the year. At MSP Intl, MN the 1991–2020 average is 28.3°F — cooler by 12.3°F.
• 'Minor Snow' is a phenological marker from the Yellow River valley — what observers saw, not a temperature threshold. The nearest thing your own record has to it: at MSP Intl, MN the first freeze of autumn has arrived by October 10 in half of years — 43 days before this fortnight begins. This fortnight typically carries about 12.0 days at or below freezing.

If Damp-heat came out high for you. Traditional theory associates Damp-heat with damp and heat arriving together, rather than either one alone. That is a theoretical association drawn from the classical literature, not a research finding. This fortnight runs to an average high of 35.2°F with rain on about 29.6% of days. Whether any of it matters for you is something to observe, not something this page can tell you.
