Full Moon Calendar 1999
Before continuing into the 2000s, we finished the 1990s with an interesting year of full moons.
1999 was a year with 2 blue moons and a black moon. The two blue moons occurred in January and March. As a result, February did not have a full moon at all. A month without a full moon is referred to as a black moon.
The December 1999 full moon also fell on the same day as the Winter Solstice. This setup a seasonal blue moon for the Winter 1999/2000 season, which will occur in February 2000.
The January blue moon also occurred with a penumbral lunar eclipse. A partial lunar eclipse coincided with the July 1999 full moon.
The dates and times are provided by NASA in Eastern Standard Time (EST) with Daylight Saving Time (DST) for part of the year. Also below is the Universal Time Coordinated (UTC) time. This was previously referred to at Greenwich Mean Time (GMT).
Note: The UTC dates show up differently for January and August because of the conversion between EST and UTC.
