It’s a challenge every month to spot the New Moon after sunset by naked eye (or eyeglasses) as early as possible. I use the term New Moon in its classical sense of one’s first sighting of the Moon after its monthly solar conjunction (Dark Moon).
The Dark Moon (which some call New Moon) will reach a geocentric minimum illuminated fraction of its apparent disk on 2021 AUG 08 at 18:30 UT (13:30 CDT).
Sharp eyed observers may attempt to spot the half-day-old Moon on August 8. Others should have much better luck the following evening. See my New Moon Spotting chart above.
Notice that these two lists are not identical. A Full Moon's nearness to the Earth is not the only consideration in determining a Full Moon's brightness.
Two other factors are the spatial nearness of the Moon to the Sun, and the angular nearness of the Moon to the Antisolar Point.
That's why the brightest Full Moons tend to occur not far from early January when the Earth is near perihelion, and often when the Moon is just touching the Earth's Penumbra around the time of a Lunar Eclipse.
