How Many Days?
The question you ask yourself every month.
One calendar always gives the same answer.
HEKA Structure
Twelve months have exactly 28 days. March (the 13th month) has 29 days—or 30 in leap years. Hexa sits between August and September. Simple, predictable, with the irregularity isolated to one month.
Gregorian Structure
Months vary between 28, 30, and 31 days. You must remember: "Thirty days hath September, April, June, and November..." or calculate fresh each time.
The Cognitive Difference
This test isolates a question you ask yourself unconsciously every month: "How many days do I have?" In one calendar, the answer is automatic. In the other, it requires memory or calculation. This friction, repeated monthly, compounds into significant cognitive load over a year.
