Every month has exactly four weeks. Within each year, every date falls on the same weekday, month after month. The year begins in April when seasons are in transition, not at their extremes. HEKA is a calendar designed for clarity.
The Gregorian calendar is a stack of historical patches. Roman politics, religious councils, astronomical fixes added centuries apart. It was never designed as a coherent system.
The HEKA year flows through three distinct arcs, each serving a different purpose in the rhythm of work and rest.
The year begins with spring. New projects, new intentions, new growth. The threshold month.
Eight months of perfectly regular structure. Build momentum. Plan with confidence. This is where the work happens.
Bring the year to resolution. Finish what you started. Prepare for the next opening.
HEKA offers two ways to calculate the year. One keeps you aligned with the civil world. The other follows the sky itself.
March has 30 days when the next Gregorian year is a leap year. April 1st always aligns with civil April 1st. Your HEKA calendar stays in step with the world around you.
March has 30 days every 4th year except every 128th. The calendar follows the true tropical year with astronomical precision. Your astrology aligns with the actual stars.
