Passover began Monday at sunset, 7:20 p.m., however the official “full” moon rose at 7:58 p.m. Wednesday. Astronomers determine a full moon by calculating the percentage of illumination, as tonight’s full moon will have 94 percent illumination. One school of thought suggests “light” was needed for the Israelites to leave Egypt, in darkness, and continue their journey out of bondage. Guiding them was a full moon, referred to as the Passover Moon. As noted in previous columns, Easter is calculated as the first Sunday after the paschal full moon or after the vernal equinox, which began March 20. Moon phase is a time-tested component when Easter occurs during the Liturgical year. Lent began 43 days ago and Easter can fall anywhere between March 22 and April 25.
