Daily phase names group the cycle into eight broad phase sectors, using progress between exact astronomical events. They describe the 8 p.m. Eastern sample, not the instant of a new moon, quarter moon, or full moon. The tables list those exact principal-phase instants separately.

“No moonrise” means no rise occurs during that midnight-to-midnight Eastern calendar date at the New York City observer location; it does not mean the moon never rises.
