East'er-dāy or Easter-day

} feast, Easter, on eastron, at Easter, D. ooster, O. H. Ger. ōstra, ōstarā, N. H. Ger. ostern, from A-S. Eastre, O. H. Ger. Ōstara, a goddess of light or spring, in honor of whom a festival was celebrated in April; whence this month was called A-S. eastermōnath, O. H. Ger. ōstarmanoth.] A church festival commemorating Christ’s resurrection, and occurring on Sunday, the second day after Good Friday. It corresponds to the pascha or passover of the Jews, and most nations still give it this name under the various forms of pascha, pasque, pâque, or pask.

Easter-day, on which the rest of the movable feasts depend, is always the first Sunday after the fourteenth day of the calendar moon which happens upon or next after the 21st of March, according to the rules laid down for the construction of the calendar; so that if the fourteenth day happens on a Sunday, Easter day is the Sunday after.
