 Starting the year on the spring equinox and using observation-based realignment days connects the calendar to natural rhythms:
 
 - **Seasonal Alignment:** Tying the start of the year to the spring equinox ensures that the calendar remains consistently synchronized with the Earth's orbit and seasonal changes, which is vital for agriculture, seasonal planning, and cultural events.
 - **Connection to Nature:** This alignment can foster a stronger connection to natural cycles (solar and potentially lunar, as a 28-day month is close to the lunar cycle), which some believe promotes well-being and environmental awareness.
 - **Logical New Year:** The spring equinox (around March 20th in the Gregorian calendar) represents a natural "reset" point when nature begins to bloom in the Northern Hemisphere, providing a more intuitive start to the year than the current January 1st.
