Ephemeris for Thursday, June 6th. Today the Sun will be up for 15 hours and 26 minutes, setting at 9:25, and it will rise tomorrow at 5:57. The Moon, 3 days past new, will set at 12:40 tomorrow morning.
Today is the 75th anniversary of the greatest battle of World War II was the invasion of Normandy on D-Day, a date governed by the position of the Moon. The full moon on June the 6th, 1944 gave light for the gliders and paratroopers to carry out their operations at midnight. Plus the high tides were near noon and midnight and the low tides near dawn. The idea was to hit the beach at low tide to enable the landing craft to operate without hitting the obstacles the Germans planted in the tidal zone. It was great for the landing craft, but the troops had a lot of open beach to cover to get to some sort of shelter. The best days for the invasion were the 5th, 6th and 7th of June. Bad weather on the 5th caused a one day postponement.
The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
