The article states the full moon will occur Thursday, Dec. 12 at 12:12 a.m. EDT (5:12 UTC). I think you have a typo, unless this was supposed to be listed in Eastern DAYLIGHT Time?

Hi, this is one of the words I learned from Scrabble: syzygy. When these three objects line up, the exact moment for it happening does not need to be at any particular time of the day at your location.
 
From Wiki Lunar month:
"Therefore, the synodic month takes 2.2 days longer than the sidereal month. Thus, about 13.37 sidereal months, but about 12.37 synodic months, occur in a Gregorian year."

So in 36 calendar months, there are 40.11 sidereal months.

Alternatively, 1 mean year = 365.2425 days.
1 sidereal month = 29.531 days. Ratio 12,368 sidereal months/calendar year.

Every 3 calendar years there are 37.10 sidereal months = 37.10 full moons.#
i.e., approx. 12 + 12 + 13 or two years of 12 full moons and one year of 13 full moons.
