This is a suggested practice (#3) for the Calendar:

Cycle through the Seasons

You're likely familiar with the four seasons: Spring, Summer, Autumn, and Winter. The calendar delves deeper into each seasonal cycle. The seasons are further divided into solar fortnights (15-day periods) and what the ancient Chinese called "Hou"—three 5-day periods within each of the 24 Jieqi.

• Begin by noting and celebrating the Summer and Winter solstices and Spring and Autumn equinoxes. For thousands of years, cultures worldwide have recognized these days as special. Changes in the celestial realm ripple down to changes in nature (and thus, to us humans). How do you celebrate these four special days of the year? What can you do to make them more meaningful than ordinary days?
• Expand your seasonal awareness with 4 more key dates: the start of Spring (aligned with Imbolc and Chinese New Year); the start of Summer (aligned with Beltane and May Day celebrations); the start of Autumn (aligned with Lammas and near the Japanese Obon festival); and the start of Winter (aligned with Samhain, Halloween, and All Saints' Day). These transitional periods mark the changing seasons—what do you notice? Observe the trees, grass, flowers, birds, and other animals around you. Notice the wind's character and the qualities of temperature and moisture. Keep a journal, take pictures, and document your findings. (Share your observations if you can!)
• Deepen your exploration through Chinese 5 elements theory, studying the connections between colors, directions, feelings, organs, and movements. How do these seasonal pulses manifest in your physical and mental being? Practice season-based Qi Gong or other movement practices to mirror nature's patterns (feel free to ask me or join a free online class for inspiration).
• For those curious to dive deeper, explore the 24 Jieqi and their 5-day periods throughout the year. How do these ancient Chinese observations of the "Hou" align with what you see in your environment? (Rather than sharing my own location-specific observations, I encourage you to make your own where you live. Step outside regularly and observe mindfully.)
• To sense an even deeper seasonal rhythm, contemplate the quotes from Suwen 2 (an ancient Chinese text): "the qi of heaven becomes urgent" or "the qi of earth becomes light." What might these mean? How do they relate to your experience of the seasons? This opens the door to deeper contemplation, which you can explore at your own pace.
