Trinity Flags are only given to nations that reside in the Triple Crown Continental zone. The Triple Crown Continental zone is encompasses the parts of Asia, Africa, and Europe that meet along the same longitude. Thus Zambia of Africa, Jordan of Asia, and Belarus of Europe get a Trinity Flag.
Odd as it may seem but these nations are tuned to similar tempo of life between breakfast, lunch, dinner.
