quote:
February 1865 is the only month in recorded history not to have a full moon.
This is a fallacy. There was, in fact, a full moon in February, 1865. It occurred on 1865 February 10 at 16:27 UTC.
The specific chart is the USNO 1865 Moon Phases document.
This is not to say, however, that it is impossible for February to miss the full phase. The moon phases cycle every 29.5 days. Februrary, with 28 days (and 29 on a leap year), does miss a phase periodically.
In fact 1866, 1885, 1915, 1934, 1961 did not have a full phase.
And
now we know everything
