What’s going on here? If I read the date correctly, it's Independence Day. June 12, 1898.

As wikipedia notes:

"In 1962, when the United States rejected Philippine claims for the destruction wrought by American forces in World War II, president Diosdado Macapagal changed the celebration of Independence Day from July 4 to June 12. Aguinaldo rose from his sickbed to attend the celebration of independence 64 years after he declared it."
