March 28, 2021
The crest of this month's full moon falls on the 28th of this month at 18:48 UTC (2:48 p.m. Eastern; translate UTC to your time). This full moon comes just two days before the March 30 lunar perigee, when the moon is swinging into the near part of its orbit with respect to Earth.
This moon on the 28th ranks as the 4th-closest (and therefore 4th-largest and 4th-brightest) of the 12 full moons of 2021.
