What Time Is The Supermoon Tonight?

A full moon will occur on Wednesday, March 20, 2019, but not just any full moon, this will be the last supermoon of 2019 that is dubbed a “Super Worm Moon” because full moons in March are called “Worm’s Moon” or “Sap Moon.”

The March 2019 supermoon also occurs on the same day as the Spring Equinox which is also the astronomical First Day of Spring.

Although the first full moon of Spring is usually called an “Easter Moon” and “The Paschal Moon,” this full moon is not considered an Easter Moon because Christian church has set the First Day of Spring on the fixed date of March 21 while the Equinox and astronomical First Day of Spring can vary from March 19 through March 21.
