April’s full moon will grace the night sky this week.

The April full moon, known as the “Pink Moon,” will occur the night of Wednesday, April 5 into the morning of April 6. According to EarthSky.org, the crest of the full moon takes place at 11:34 p.m. CT.

The moon will appear full and very bright for the nights leading up to Thursday.

April’s full moon is known as the Pink Moon due to the flowers and trees that bloom in the spring, particularly pink creeping phlox.

According to the Farmer’s Almanac, the Pink Moon is also known as the Full Sprouting Grass Moon, the Egg Moon and the Full Fish Moon, as well as the Breaking Ice Moon, the Budding Moon of Plants and Shrubs, Moon of the Red Grass Appearing and the Frog Moon.

This is the also Pesach or Passover Moon. Pesach or Passover begins at sundown on Wednesday, April 5, and ends at nightfall on Thursday, April 13. The Seder feasts are on the first two evenings of Passover.

In the Christian ecclesiastical calendar, this is the Paschal Moon, from which the date of Easter is calculated, NASA explained. Generally, the Christian holiday of Easter, also called Pascha, is celebrated on the first Sunday after the first full moon that occurs on or after the spring equinox.

The spring equinox was March 20th.

However, there are differences between the times of these astronomical events and the calendars used by the Eastern and Western churches. This is one of the years where these differences matter. Western Christianity will be celebrating Easter on Sunday, April 9, the Sunday after this first full Moon of spring. Eastern Orthodox Easter will be a week later on Sunday, April 16.
