February 29th, the twenty-third day of the first lunar month, Old Almanac: Auspicious for weddings.
It was also a coincidence, occurring on the leap month that comes once every four years, and on that very day!
The wedding of the Little Eldest Princess of the Empire, the Holy Emperor's own sister, was an exceptionally grand affair, even if it was just an engagement ceremony.
The Quasi Prince Consort had been welcoming guests since early morning, busy until evening before he could catch a moment of respite. Not to mention rest; his hands were tired just from receiving gifts.
However, almost all the gifts were for the Eldest Princess.
Understandable.
