February Blue Moons: Is it even possible?

While it’s impossible for February to have two full moons because the month only has 28 or 29 calendar days, depending on the year, a February Blue Moon happens when winter has four full moons.

Two full moons in one month is the most common definition of a blue moon. The other definition of a blue moon is the third full moon in a season with four full moons, sometimes referred to as a seasonal blue moon.

On an extremely rare occasion, the calendar lines up in the right way for Winter to have four full moons, making the full moon in February a seasonal blue moon.

When is the next February Blue Moon?

The next February Blue Moon will occur on Thursday February 18, 2258 8:48 PM EST or Friday February 19, 2258 1:48 AM UTC. It will be the second full moon of the Winter 2257-2258 season and the second full moon of 2258.

It will be more than 200 years before a February Blue Moon is seen again because the calendar needs to align perfectly.

In order for there to be four Winter full moons, the December full moon needs to occur within a couple of hours after the Winter Solstice. It takes approximately 88.5 days to go from a full moon to a fourth full moon. Winter has approximately 89 days.

There is almost no wiggle room in the calendar to fit in four full moons during the winter season, and looking at the calendar year over year, it was close, but the calendar would miss by hours.
