They say,
"A full day is a period of 24 consecutive hours, beginning and ending at midnight. You must spend the full day in a foreign country or countries for that day to be counted. ...Example: You leave the United States for France by air on June 10. You arrive in France at 9:00 a.m. on June 11. Your first full day in France is June 12."
