With regard to months, I'm just happy only February has 28 days (cheers for leap year) because every month would have the same calendar and every Monday would be the same day. So totally boring! Amazingly to me, people don't register the fact that March has the same date pattern as February! (Non leap year, of course).
Yes, I should have realized I knew the Chinese Zodiac. Our local Chinese restaurants have placemats with the "Year of the Rat" etc on them.
